[Q] Bluetooth Audio Quality Issues Fix?

Hey guys,
I've just got droid charge last week and I like everything about it (only after rooting and installing Gummycharged), but there is one huge problem for me. Well, it might be 2, but one of them is slightly better with Gummycharged and voodoo lagfix.
Here's the issue - I love listening to music in my car through bluetooth and until recently I've been using my Ipod touch 4g and it has been working flawlessly and music quality was great. Now, once I got the Droid Charge, I've noticed 2 things - every minute or 2 the songs would skip (interrupt), and the sound quality was pretty terrible (mainly with the high end - sounded like tweeters were being overloaded).
Rooting the phone helped with skipping - it now happens once in 10 minutes or so, so that's acceptable, however the sound quality is still pretty horrible. I've looked around on these forums and people had similar issues with quality with their stock phones and most people suggest CyanogenMod. I'm not all that familiar with what different ROMs are available for Charge, but as far as I can tell this one isn't. Does anyone know if there is way to fix/configure the quality of bluetooth transmission on this phone? Is there any mod I can install? Anyone having similar issues?
Any help is much appreciated!

Have you looked at this thread? It's more about disconnections, but the fix they list might help you, too.

Thanks, but the problem is more fundamental, I suppose. Looks like HTC and Samsung use some custom bluetooth code in their ROMs. Apparently it limits the bitpool value at 32, which makes the audio quality terrible over bluetooth. Surprisingly, everyone knows what the problem is but so far the only reported solution is the cyanogenmod.
Here's more about it:

Wow, nasty and long standing! Glad I didn't buy one of those headsets like I was going to. *sigh*

Hey guys,
I'm running GummyCharged 1.85 w/ the voodoo kernel (pbj) and also getting skips over bluetooth to my car stereo. It's seriously distracting and annoying. My Droid 2 worked flawlessly in this respect, but it seems like any time the Charge does any "thinking" it makes the BT audio skip.
Any hope of a fix for this?

My Charge is stock and I haven't had a chance to try the bluetooth audio streaming yet, but when I plug my phone into my car to listen to music through the aux jack it does the same thing, about once every song it skips. Seems odd. I'll try bluetooth today on my way to school and see what happens. You'd think with Bluetooth 3.0 on board the signal would be strong enough to stream decent quality music...
I can confirm this issue is there and in your face a lot. I tried it on the way to school (about a 40 minute ride), it skipped once or twice every few minutes, no big deal. The quality was acceptable for wireless transfer, nothing to write home about. Not a lot of low end, and just a hint of static and slightly over-boosted highs. However I tried it again on the way home once I realized I had forgotten my aux cable, and it skipped so often I just switched to FM. It was so annoying. I can confirm your suspicions that it seems to happen when the phone is trying to do something. Switching towers, background apps, turning on data and checking traffic with Google Maps really freaked it out, but it was fine once I was done. Kinda sucks for those who wish to use the feature regularly.

Update?
I have a droid charge, and the bluetooth streaming quality really sucks, like the OP pointed out, highs are really bad.
Tried with my friends iphone and it worked flawlessly.
CyanogenMod is still unavailable for the droid charge as far as I can tell.
Is there any other fix that anyone has found that will fix the bluetooth sound quality when streaming music?
Any help or places to look is appreciated.

Persistant Volume Issue in Gingerbread

Quoting from another thread, apparently I'm not the only one with this issue so I'd like to dedicate this thread to finding a possible fix (PS, if someone can suggest a better title let me know).
open1your1eyes0 said:
Hmm maybe it's just me but I think I discovered the oddest bug ever. For some reason, the first sound I hear after like 30 seconds of idle is quieter than what I'm set to in the volume settings and then if I keep using the device without idle all the sounds are loud like normal after that first sound.
For example, I have the device locked with screen off for a while, I unlock the device and the unlock sound is really quiet, then I immediately lock it and unlock it again and now the sound is loud like normal. I keep doing that and it sounds fine each time after that, but as soon as I lock it and leave it idle for like 30 seconds or more and unlock it again, the unlock sound is quiet again.
Also this doesn't only affect the unlock sound, it affects everything, notifications, alarm, ringer, etc....and all my volume is set to maximum I even checked with a 3rd party app. The same thing happened on the previous 2.07 and 2.10 leaks, it's almost like Gingerbread introduced this weird "automatically lower master volume after idle mode". I can't seem to find any option that would affect it.

So basically the first sound you hear after a short or long idle time will always be quieter than your actual setting and then keep using the device and everything sounds normal. I almost overslept and missed calls several times cause my alarm and ringtones are so quiet now.
Anyone have any ideas what could be done or taken a look at here?
EDIT: FYI, someone else claimed they had it since MR1 update but I had no issues on Froyo whatsoever. This only became introduced to me with the first 2.07 leak.

I've noticed this as well. I didn't find it to be a big deal, but thought I'd share.

all i know is even with volume+ the volume sucks on this phone. my wife's lg vortex is 5x louder. we need a dev to look into this.

I honestly thought I was alone on this one. I miss texts and calls all the time because the volume is so quiet after idle.
It is easy to see this with gingeritis all you have to do is turn the volume up to max for your ringer, and then turn the screen off and let it sit for a minute or two. Then turn the screen back on and push the volume up key, you will notice the first sound it makes is really soft, and if you push it again, it makes the normal loud sound.
I hope someone sheds light on this...I for one would like to stop missing calls
I am about to try the official RUU and see if it still does it, but it's only done it since I started using gingerbread roms.

aosp roms are louder but not loud enough. we for sure need a volume boost. i cannot imagine it would be that hard to do.

I was just getting ready to start a thread about a possible volume booster.. I can't remember if it was the tb or fascinate i had it on but, adrynalyne had a program called drm i think in his roms that enhanced the volume.. the problem I'm having is the media volume.. I'm trying to listen to MLB at bat here at work but can barely hear the broadcast.
Sent from my ADR6400L using XDA App

Hmm volume booster does seem to be a good workaround idea but I think the main issue is the fact that the volume level automatically changes regardless of the volume loudness. If only someone might be able to figure out what this can be caused by.....
Also I noticed something interesting today. On some sounds it actually seems like it starts off quiet and then makes it louder while the sound is playing. It's hard to tell cause it's so fast but it's definitely noticeable in some cases.

On cm7 there is an option to play notifications and ringtone through the speaker (even though I thought they did anyway) but I haven't noticed the problem with that selected.

someone should look into the lg vortex volume and try to port the mod over. my wifes phone is 10x louder than my tbolt. hers is aosp too.

FYI, I have only tested this on the official leaks. No custom ROMs or AOSP yet. Though I'm quite tempted to find out if this occurs on other ROMs as well (especially AOSP).

It takes a split second for the audio amplifier to fire up. The kernel is probably not accounting for this. The audio amplifier suspends after usage just like the screen does to prevent battery drain.

Hmm that's an interesting theory but just FYI, the screen times out later than the volume begins to idle to quiet (if it matters). You think flashing another kernel might fix the issue?

Sorry. I didn't mean they time out at the same time. Just meant that it also suspends to save battery. I have a feeling this won't be solved until the gingerbread sense kernel source is released. A really good kernel dev might be able to look into this with their current source. You might also notice a pop or crackle sound due to this same issue. Again it is coming from the amplifier powering up WHILE the audio is playing instead of BEFORE. There could be an underlying latency in the hardware but I doubt that's true since it wasn't really noticeable on Froyo. Android has always had a problem with audio latency although it has been pretty much "worked around".

Hmm I see. FYI, I also noticed this issue is extremely obvious when opening the phone dialer for the first time and just press like the number 1. You can hear for a split second as if it "boots up" the audio amplifier the dialing sound for the button grows from silent to normal volume. Then as you dial the rest it sounds fine. But cancel out of the phone dialer and back into literally after like as short as 5 seconds press a number on the dialpad again, you hear it making dialing sound quiet to louder and then normal for the rest of the dialing.
Such a bizarre issue, I really don't understand why this problem just occurred in Gingerbread builds if it's been absolutely fine on older Froyo builds. You would think something as obvious as this would be one of the first bugs they try to resolve. And it seems like it wouldn't be that hard also (assuming it's just a setting in the kernel coding or something).
FYI, if it helps anyone willing to look into it I found out the audio amplifier for the Thunderbolt is a TI TPA2051.
I am really hoping some of our higher up guys can take a look at this. I am really curious to know what (if anything) can fix this issue.

i do know the overall volume on sense roms are much quieter than aosp. what a waste of a good speaker. we for sure need a fix here.

It might not be as easy as it sounds. Audio can be handled quite differently from OEM to OEM. I'm not sure if the thunderbolt is using the native Android audio or if HTC is using their own implementation. You also have to throw the audio Codec into the mix. Here is a link that although it doesn't explain our specific problem, you can see the complexity and the inherent issues with Android audio http://groups.google.com/group/android-ndk/browse_thread/thread/1744088af0924ed9/7170773c13aabe2f i'm not sure about now but the general consensus with audio developers used to be that google needed to stop trying to implement fancy bells and whistles in the audio and get a good solid foundation to start with. Gingerbread was supposed to address some of these issues but I don't believe it did.
Anyway, i'm not positive but you may notice the problem more in gingerbread because there were quite a few changes in the native audio implementation.

Gingerbread Kernel Source for Thunderbolt just released: Link

I know this thread is old, but something i've noticed in regards to this. Im running a semi-stock ROM (xda-bolt), with a stock kernel. I noticed the volume changes don't happen on this ROM, however with a modified kernel such as IMOs 6, the problem arises. Any other non-stock kernel i've used has this problem, but stock kernels do not.

Quick Question

So im running CM7 i believe and it is rooted everything is good on my phone just a couple of quick questions about things that seem to be annoying me.
1. Does anyone else's phone seem to heat up pretty quickly with extended use? For example if i've got the screen on and I'm texting for like an hour straight it gets pretty warm to a hot sensation right on the metal part that holds the SIM card in and the SD card. The phone also heats up when its charging too, i'm assuming that is normal.
2. I have ADW Launcher and the Cyanogen Mod or whatever it's called. The issue is that when I'm playing music and get a text my audio will completely pause (but the song keeps going) and then keep going which tends to get annoying when I'm enjoying a part of the song and I miss it entirely because of a notification. I've tried to set it up so that it ducks the audio 4db but it doesn't seem to work for me. Does anyone know how to fix this?
3. Sometimes when I receive texts i can hear it through my speakers of my computer coming but my phone will never fully "receive" it so it sits in limbo forever. Does this happen to anyone else?
4. Battery problems, it seems to die a little quicker than i'd like. I've got it on the lowest brightness, no internet, no bluetooth, no gps, wifi usually on but when i'm not near a wifi hotspot i turn it off. Is there a solution to this?
Thanks for any help in advance

Overheating is pretty much the norm on the G2X. Perhaps there are other ways to deal with this, but one way for sure is to go to settings-->applictions-->development and click stay awake. This reduces the overheating while charging. If you get a lot of overheating it might be the battery.

I've tried to notification duck but it doesn't work. It's on right now but when im watching a youtube video or something it still cuts the audio out completely but still plays it while i listen to my notification ring
Also, once a phone is unlocked it is unlocked for good right? Even if i put different ROMs and such? Cause i bought this phone 2 months ago unlocked with it rooted and flashed with this stuff. I'm asking because I'm scared that if i try putting a different ROM on it that won't be unlocked anymore. I don't know the unlock code or anything lol
Edit: And i know the G2X camera is bad so I'm wondering if there is a way to make it permantly increase the exposure to +1 or +2 instead of me having to change that every time i open the camera app or is that not possible?

also im thinking of ditching the g2x all together for the samsung galaxy s2 do you guys think it is worth it? I don't know if the S2 has any problems as bad as this phone. It's going to cost me 100 dollars to upgrade to it in the end. Thoughts?? or maybe the samsung galaxy nexus

If your phone was unlocked (not the same as rooted) it will stay that way. ROM away as you wish.
Unlocked = can use on any SIM based carrier
Rooted = means you can do whatever you want to your phone software-wise.

I myself have the heat problem but it was partially fixed when I decided to mess the overclocking and undervolting made available by custom kernels. To fully fix this problem with my phone overclocked to 1.4ghz and undervolted I took some aluminium foil layered a few pieces together and cut it to the size of the back. I added a bit of extra aluminium to where the sim is because it seems like that is where most of the heat comes from and now my phone becomes warm but not warm to the touch now that it can disparate heat faster.

Very nice idea but wouldn't the aluminium retain the heat to the battery causing it to overheat

I don't know but I have not had any problems with it so far and its been almost 3-4 months with this small mod.

I rooted a friend sgs2 for him. its through sprint. so far it doesn't seem very great semi laggy and I would not want 1. Sprint internet seems very slow as well. My g2x puts his sgs2 to shame. I did leave him on stock rom though so maybe it would be better if I souped it up

I am. I'm looking for suggestions for things to try and improve the stuttering/skipping/dropouts that I'm experiencing when using my OnePlus One in media playback mode through my Chevrolet MyLink car radio. I have some additional details to offer and things I have tried:
1) The playback application doesn't seem to make any difference, the problem is most pronounced (unlistenable) when playing back music files and is highly annoying when listening to speech (e.g. podcast) files. I suspect the difference is the music having a beat that gets interrupted while there are some normal pauses in speech so the stuttering blends in a bit more. In any event, it's not a problem with the playback application.
2) It seems unlikely to be a problem with the car radio (Chevrolet MyLink). Though I haven't done extensive testing I have done some using my old Motorola Atrix HD with a nightly CM11 on it from a few weeks back and that does not seem to have the issue, or at least it is not nearly as severe.
3) When I use a third party bluetooth audio receiver (some cheap no-name one from ebay) the quality seems to be fine but when I try to go directly to the car stereo I get tons of stuttering/skipping/drop outs.
A friend suggested that I try running an alternative kernel and see if that improves things. Any ideas on whether that may be the case or which one might be the best to try? Any other suggestions? It's quite annoying that I can't playback audio through the car radio...
Thanks!

Anyone have any ideas? I tried running the Franco kernel tonight and it seems to have the same issue. I did some logcat captures and I seem to be getting a lot of "W/bt-btif ( 2104): btif_media_aa_prep_2_send congestion buf count 24" messages when playing back audio through the car radio. See the attached full logcat captures with both the stock and Franco kernels and connected to both an alternative Bluetooth dongle and to the MyLink car radio.
Any suggestions?

After further testing I was able to determine this is an issue with the phone and not the car radio as I was able to find at least one other BT device which exhibits the same issue. I have created a ticket for this issue at: https://jira.cyanogenmod.org/browse/BACON-1005 if you are also experiencing this issue you are encouraged to go and vote for the ticket.

One question though. Do you have WiFi on when traveling in your car? Try turning it off and see if you still get skipping.

I do in fact have WiFi on at all times. I tried turning it off for the day today while doing some driving and it appeared to clear up the problem. I would think it's still a bug because having WiFi on should not prevent BT audio from working correctly but it at least gives someone a direction to investigate.

So I've done some slightly longer term testing and what I can say is the problem is not totally cleared up when WiFi is off but it is much, much better (definitely listenable). I will still get a couple dropouts when first starting a stream (sometimes, not always) but after 30 seconds to a minute it seems to settle down and be fine as long as I keep the WiFi off.

Just to clarify the situation..
My Xperia Z2 have the same issues.. It is not your phone but the Bluetooth stack in android that pretty much sucks the problems you are dicribing has been there since android 4.2 on a lot of devices.
I have just changed my Lumia 1020 out with this Z2 and call me disappointed in music quality! On the Lumia you would have trouble hearing a difference between jack/auxiliary and Bluetooth..

And today I did notice some dropouts even with WiFi off well into my drive but it was just a few packets I would guess more of an annoyance than a serious problem. I've heard about issues in the Android BT stack but the confusing part of that is why certain devices (such as my Atrix HD) don't seem to experience the problem.

I have a bluetooth stereo I use every morning in my home and a bluetooth stereo in my car. I almost exclusively use pandora, but I have also used power amp on longer trips. I have never experience this issue with my opo. I have ran 25-33 all rooted with no problems and am currently using CM11 nightlies. I also am not having any wifi issues.
Sorry it's not very helpful, but it doesn't sound like a widespread issue at least.

It certainly has something to do with the particular bluetooth implementation used by the receiver interacting with the OPO. As I indicated I have three different BT receivers I can test with and the problem affects two of them but not the other.

[Q] Nvidia Shiled Tab weird noises?!?

I recently got my Nvidia Shield for Christmas and upon installing the ATT LTE data Sim I seem to have a crackleing sound when using data. It does not make the sound while not using data example just playing music or games but it will if I'm listening to music and say... Search the web or anything like that. The noise doesn't happen when using WiFi or listening over the tablet speakers.
I have another sound problem that occurs seldomly when playing music over the speakers (both with WiFi and LTE). The tablet makes a, what I call, transformer like noise; the noise to the best I can describe sounds like a medium tone zap not high pitched.
Does anyone else have these problems and how do I fix them/do I need to sent this one back?

Is this the sort of thing you mean?
Thanks

I get the digital sound stretch/squelch "transformer" noise you're referring to sometimes. I'm not sure how you'd fix that: I think it's a quirk of this tablet.

I don't have the crackling happen to the speakers only the squelch.

I get it some times, I've had it happen when there are a lot of apps going, and if an app hits high cpu load it seems. It'll do it for a moment, and clear up for a while. Closing down the backgrounded apps seems to help me. YMMV
Edit: You running latest update? I noticed it start after the 5.0.1 update.

I've had this same issue on every version of the OS. I've had the tablet since a week after release in August and have run every update on the tablet and still get the noise, sometimes it is rather loud. It seems to do it more when stressing the tablet, I used to have Real Racing 3 on the tablet with the graphics modded to run at their highest, it would occasionally freeze up, and when it resumed, the speakers would squeak nearly every time.

I may not have just noticed it prior. But yours appears to be the same that mine is doing.
