[Q] Bluetooth issues - Nexus 5 Q&A, Help & Troubleshooting

Is anyone lse having problem with bluetooth. I paired my nexus 5 with my car without problem but when I stream music I run into issues. At first I thought only the left channel was coming through but then I realized the right channel was there only with volume so low it was barely audible. Also, adjusting the volume on the phone (for the bluetooth output) has no effect on the volume.
Any ideas?

I just got mine tonight i will sync with the truck tomorrow morning and let you know what i get i hope it works smooth i know in the past i have had issues with nexus phones syncing with the factory system that i didn't have with other android and ios devices.

I have the same sort of issue with both home wifi and my car bluetooth...only a power cycle efficiently works...sometimes a radio cycle fixes it...very annoying

Voice calls over bluetooth (Ford Escape) are very jittery on my side. The receiving party can hear my voice clearly fortunately.

[Q] HBS730 + Sound Playback = No Muting Audio

Hey Folks,
Having an odd one with my new perfect nexus 5. I use the LG HBS730 BT Headset and while I play any sound I am unable to fully mute the audio. I tried lowering it via the volume on the phone and headset. It lowers but not mute it fully, the low volume is still pretty loud.
Anyone else tried this? Works perfect on my old phone as well as my iPad, when I lower it fully it'll mute but not on my nexus.
Thoughts?
Btw tried it with Google Play Music and YouTube, same issue.
The HBS730 is loud as hell on its lowest setting. The 700 is normal. The reason it is so loud on the Nexus is the Bluetooth is now linked up volume wise. The problem is the 730 not the nexus.

Its not about being loud my issue, its the fact that i am unable to mute the audio. I can do this on an HTC One XL, S4, and iPad.
With the Nexus, i cant mute it.

I could mute mine on 4.3, but not 4.4. Like I said, the OS in 4.4 now links up Bluetooth Volume level to the media volume level. This leads to it being unable to be muted since you can't turn down the volume past the lowest the headset offers. The closest thing you can do is pause, but that's it.
FYI, I have 2 HBS730's, and a HBS700.

Any fix? I am using an equalizer as a workaround but it's kind of inconvenient. The equalizer app sometimes got killed and then the volume jumps (and so do I)!
I have this headset and I love it. unfortunately I have the same problem in that even on its lowest setting its pretty loud.

What to you mean???Elaborate what???
I am having this problem as well. After using my Bluetooth headset the volumes will not return to the levels I had without the Bluetooth headset connected. It also happens on my Galaxy Nexus running Kit Kat so I think it is an OS issue. I do notice that the volume icon that comes up on the screen when attempting to change the volume is different than normal as it doesn't have the 2 "soundwaves" coming out of it. I have yet to find a fix other than turning the phone off and back on.

Google results suggest that the problem may be due to dirt in the jack.
I tried an app about a minute ago, that called SoundAbout and seems is a good temporary solution for the problem. If someone else tried something else and it worked for him please let me know.

This same thing happens to me. Its weird whenever i connect my bluetooth the audio starts to come out of the device's earset (where you put your ear). I have to restart the phone to fix it until I connect a bluetooth again. When I use the volume buttons I see a different bar (like when you are on a call or something) instead of the bar to adjust ringtone's volume. It is super annoying. Sometimes music comes out of the speakers but if I open an app that speaks over bluetooth (waze for example) the music audio stops coming from the speakers and starts coming out the ear speaker on the phone..
What I do to replicate this is to connect a bluetooth headset. Turn on music (google music) open waze.. Audio starts coming out the ear speaker instead of the phones speaker..

Did you find any other solutions for the problem?
I too have this issue. Same on two handsets. Connect to bluetooth and works fine. Disconnect and all future audio comes out of earpiece hole until you reboot and then back to the speaker.
Anyone found a solution for this? I have the same problem.

I may have a workaround for this issue.
This problem has been driving me crazy. The first time after a reboot, my Nexus 5 connects to my car audio just fine via bluetooth. But after I shut the car off, the phone's speaker is turned off, and all audio plays through the earpiece. Additionally, the next time I try to connet to my car's Bluetooth, it will no longer play audio through the bluetooth connection (although I can still control the device via bluetooth).
Rebooting the phone fixes it, but it's a pain to always be turning the phone on and off, and if I'm already in my car, it won't re-establish the connection if I restart my phone while the car's still running.
I downloaded the free 'Fast Reboot' app, which essentially closes and restarts all core user processes. Sure enough, launching 'Fast Reboot' seems to fix the problem... at least until the next time I disconnect.
It seems something in Kit Kat is locking the audio to the earpiece after a bluetooth disconnect. I've got my fingers crossed that the upcoming Android update fixes this problem for good. :fingers-crossed:
In the meanwhile, let me know if Fast Reboot does the trick for you too.
Thanks for the workaround, it works well. I think google will fix this in the next update, it only says "Bluetooth fixes" right now but what else are they gonna fix? Well, i hope they will.

Anyone have Bluetooth distortion issues??

Hey everyone,
Found out my company is ditching Sprint for Verizon which means I have to part with my beloved Nexus 5.
Anyway, from what I've been reading on here it seems like the M8 is really the only Verizon phone that can be rooted. I've had a few HTC phones over the years, including the M7, but they never seem to get along with my car's stereo. The phone part works fine but when I stream music via Bluetooth there is always a great deal of distortion in the high end. Especially on cymbal crashes. This makes it pretty much unlistenable. I'm curious if anyone has experienced anything like with with the M8? I've Googled it a few times and found threads about the One X and One M7 having this problem but have yet to see anything about the M8.
I don't stream to my car often, but on the handful of times I have, I didn't notice any sound issues. This was using Pandora and Google Music, on a Ford (2008 model).

Just got my jaybird x's today and guess what. Filled with static. I could not be more annoyed with this particular phone right now. Three defects in one model I mean come on. Speaker crackle. Screen is creased and looks like you're pressing down on a TV and now Bluetooth has static

I can't say for certain, but I imagine bluetooth audio issues would most likely be due to whatever is actually playing the music, not the phone. Bluetooth audio, in general, is terrible - unless you're using something like the HTC Stereoclip which does not use that same audio codec that just about everything else does. You could have lossless flac files on your phone, and 9/10 times it's gonna sound like crap over bluetooth, no matter what the music is being sent from.
I stream daily over Bluetooth and it sounds amazing. Vzw.

Just plugged mine into my aftermarket JVC GPS stereo on a my truck which gets only occasional use these days. Have to say I was somewhat blown away when I pushed some Comfortably Numb into the 5 speakers (Inc sub) and cranked up the volume. Most impressive...
The wife gets terrific sound from her N7 to some small bluetooth speakers we got last year and has no issues unless she's using TuneIn at which point it goes from OK to awful.
I say this to simply point out that the invariable rule of YMMV seems to hold sway here but I don't think the M8 has any generic systematic failure with bluetooth audio.

This is true. But I'm talking hiss/distortion like a speaker is blown. I'm just streaming Spotify to my cars stereo and not expecting flawless audio but the issues I have with the M7 were unlistenable.

From what I understand, it has something to do with HTC setting the bitpool value too low. Which, in itself, might not be a big deal but it might just be a issue with that value combined with my car's stereo. I just don't want to lose root when I move to Verizon.

Maybe the stereo in your car just sucks? Streaming Pandora over BT in my car usually sounds great. I mean granted it's not as good as using headphones, but it sounds pretty damn good.
Also, I streamed some more over this last weekend, and while the quality was still good, it did disconnect once for no apparent reason. And once it happened, I remembered that it happened a few weeks ago as well. Same thing, I was just driving along both times, and my BT just seemed to shut off. I turned BT back on, reconnected Sync (it's damned annoying how Sync never automatically reconnects), and it worked again for the rest of the weekend.

I saw that an OTA for the M8 pushed out today (I think) that was supposed to fix some Bluetooth issues. I won't if the disconnects were addressed.
I'm M8 should be here on Monday. I really hope it works out OK. I don't want to send it back for an iPhone. :crying:
Another OTA? Has anyone else heard this? I am having a really rough time with bluetooth headset outgoing voice quality so some sort of fix would be awesome.

If the phone volume is at max it will distort. When I turn the volume to max while streaming Bluetooth to my car stereo it sounds crackling and distorted. Turning volume down 2 clicks to about 85% on the phone fixes it

Again, sorry, but it may just be your stereo. When Bluetooth streaming to my car I always have my phones media volume maxed and I control the listening volume via the car volume, and it sounds fine.

Do you have an aftermarket stereo? I've had 4 different head units on my car, all high end Sony and clarion and all had same thing with max volume all my previous 3 phones ( rezound, s4, and m8). Just curious if it's just aftermarket decks that have this issue which I really don't consider an issue. I prefer to have the volume lower on the source and let my deck and equalizer provide the output anyway.

No, it's a factory Ford stereo. If you know someone with a factory BT compatible stereo, maybe try pairing your phone to their car and see if streams with or without distortion?
I mean, it's possible your particular phone itself could be bad. I just don't think it's all M8's since I don't have a problem, and because I imagine we would have seen a lot more complaints.
For six months I have been playing music in my car with a one (M7) via Bluetooth, with very annoying vibrations that eventually damaged my car stereo. I just found out that if I launch the media app via the "HTC car" app, the volume is much louder and I don't have those vibrations anymore. By default the HTC car app in the M7 only includes the default "Music" app, but other media apps may be added.
Hope this may help for the M8 too.
By these vibrations detroyed my car stereo, and I had to change it. I am pretty annoyed that HTC doesn't mention this anywhere, and leaves it to the user to find out.

Low audio thru BT??

Anyone else notice the audio output via BT to be rather low? Connected this to my card (Ford explorer) and I have to almost double the speaker volume from what I had used with my Note 3..

Had this problem today in a 2014 Dodge. the G3 has separate BT volume. SO basically I had to max out my phone volume to make it normal.
Thought i'd mention this just in case you missed it.
BT headset volume is fine but music playback through my car BT is pretty low. Like what was mentioned you need to make sure the BT volume on your G3 is turned up all the way or you will have no bump at all.
I've had lower volume issues with a wired headset. It's like I need a booster.

I have the AT&T version and I flashed the zip.
Works much better now.
Have you guys tried the XPOSED module Viper4Android app? I believe it has a way to boost the overall sound for headphones, phone speaker, Bluetooth, and USB Dock (all independently). It also has lots of other great sound tweaks too.
EDIT - Viper4Android isn't part of the xposed framework. It does require root, but otherwise is a regular app.

Afte rooting I installed Viper4Android and everything is amazing! I haven't ran Bluetooth but my headphone sound has increased 10 fold.
Compelling. I have hints of a minor problem with a wired headset volume. But I still feel there's no overwhelming evidence that returning to stock is completely dependable for the 850d.
Sent from my LG-D850 using XDA Premium 4 mobile app
I just wanted to clear up some mis-information. The Viper4Android app does not require the Xposed framework. I installed it while working with other modules and incorrectly associated it with xposed in my mind. But it is a freestanding app, not related to xposed. It does however require root privileges.
I just wanted to mention that since I posted some inaccurate information above.....

When youre connected to a BT device the volume control is for that BT device or connection.
I am on a custom ROM by Fulmics and my BT volume for calls is about 1/3 as loud as for streaming media.
Notifications are normal, it started when ringtone was quieter when BT was on, rings through BT and barely through phone, previously it rang loud on phone and just noticeable on BT... I use the BT for work and I can't have me not hearing what support is instructing me to do on a service call...
Will look into dev mode and tweaks and see if something is there to correct this low volume.
Yes I noticed this and there is a build.prop perameter that can be changed it's called : ro.lge.bt_gain_control_factor
I belong the factory setting is 0.8 I have mine set to 1.4 without issue but YMMV

I also noticed the same thing yesterday driving home. I did not have this problem earlier in the week. I'm not sure what is going on. This along with a strange wifi problem has recently surfaced. If I leave my wifi range and then return, it does not want to reconnect. I have to toggle the airplane mode then wifi will reconnect.

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.
