[Q] Bad audio quality with Bluetooth music playback - Windows Phone 7 Q&A, Help & Troubleshooting

Hi i use a Mozart 7 with Bluetooth device (sony ericsson MW600)
a very bad quality sound is produced when linked with my bluetooth device
(crackled/distorted, a low pitch noise at the background, sounds like interference from other things) - ive tried it on everywhere its the same
But it sounds perfect when its wire connected
Ive gone through several forum to find that im not the only one suffering from this. Was wondering if anyone has any solution for this or when there might be a fix for it?
i know there is a same thread about this on the HD7 forum:
http://forum.xda-developers.com/showthread.php?t=843593
But i thought the people over here could take a look at it because it seems its not just the HD7, the mozart 7 and others have all shown similar problems

i5700 sound issue problems

I searched the forum and i didnt found the answer and appropriate topic-
Me and few of my friends having Spica, we are experiencing problems with really bad sound quality - each mp3 played by system player or other players like meridian or cubed has some pops, or cracks in different moment of playing.
It sound very simillar to cracks on old vinyl/LP records.
Also on the speaker i have those cracks not only on headphones.
I had this issue on 1.6 on 2.1 clean software, and also on LeshaKs custom kernels.
I think its an software problem(maybe driver?) because more of those sounds appear when Spica is using 3G or Wifi or if its heavy loaded. Some of my friends get rid of this by installing new kernel but for me it doesnt work, also in one case two of my pals get rid of it doing nothing on the phone - it just disappeared one day..
Any ideas whats wrong with this phone? Maybe some1 found the solution already?
Because its really annoying and i cant listen to music
Not had that problem with mine. Running original 1.5 the phone shipped with
Sent from my GT-I5700 using XDA App
I noticed this as well, the weird thing is that the blips increase in frequency when i use my regular headphones instead of my in-ear headphones...
maybe it doesn't have enough power to drive the big speakers... I really wouldn't know, but using in-ear headphones drastically decreased the cracks and blips.
see if it works out for you.
My brother and GF both owns a spica and they don't have this problem. bring it back to where you bought it from before the warranty expires.
Blu Algae - Hmm maybe ask them if when they turn off the phone that crack sound appears from speaker? Even if that happened just once?
Cause I have it quite often..

Bluetooth background noise

I found this on phandroid to explain what I'm talking about,hopefully an update fixes this or I will have to send it back to Htc.http://androidforums.com/htc-sensation-4g/375199-white-noise-bluetooth-htc-sensation-4g.html
I have the issue as well.
This thread also describes a sort of similar or related problem.
Ok I see it's not just me.Hopefully it can be fixed with an update,hell I bought a new bluetooth because I thought it couldn't be the phone.

I also baught a new Bluetooth headset, a Plantronics M100 with dual mics!!, thinking it'll solve it. The noise is less, but is still there. My HD2 & Desire S when connected to the same Bluetooth headsets have no noise at all.
i have this very anoying same issue.
is there any way to fix it?
I'm using a Samsung and it works good with the sensation no background noise but if I move the phone or my head too fast I lose signal for a second
has anyone figured a fix for this , i too have the white noise when i use my bluetooth on my aftermarker stereo, i used to use this all the time with my vibrant and had no problems but ever since i got this sensation the caller on the other end complains that its horrible
bringing it back
I have this problem also. Still unresolved?
I have the exact same problem. Hoped an update to ICS would solve the problem, but it didn't.
My HD2 and DesireHD do not have this problem with my Volvo.
I thought it started after the first time I used my phone as MP3 player and putting the earplug in. That's the first time Beats Audio is activated I believe.
I'm guessing that's were the problem lies (but this was already back in November).
It might also be an app that I installed . . . can anyone trace something back to when it started being bad?

[Q] Headphones for Windows Phone Devices?

I know this should probably be posted in my device's forum (Samsung Focus), but I figure more people will probably look here and the topic about headphones in that forum is pretty dead.
I'm looking for headphones that are 100% compatible with a Samsung Focus, or any WP7 for that matter (I might be upgrading to a Focus S or a Titan - not sure yet). I don't want anything too expensive, I just want there to be volume up, volume down, pause / play / next / previous / answer call, and a microphone. I currently use iPhone headphones (as I bought my Focus used and never received a headset) and everything works except for the microphone and volume buttons (I'm surprised that much works).
So can anybody confirm 100% working headphones with the Focus / any WP7 device? Again, I am sorry that I'm not putting this in the right forum but that one has been dead for a few months.
EDIT:
I've looked at headphones here, but nobody has posted reviews on any of the headphones.

Hi Diablosblizz,
I use a simple A2DP receiver and then use whatever earphones/buds that i preferr at the time. All of the controls that you desire are held in the receiver unit and as i say the earphone type/price/quality remain your choice.
Hope this helps,
Creamy
I totally agree with last answer...the jack plug on my phone is dead from first day so i bought a 20€ bluetooth headphone (msound brand)...everything you need works, just an annoying thing since mango: music stops 10secs when a new message coming.

So, basically it is a Bluetooth device that connects to the phone and then I plug my headphones into it? I'm curious as to if this will continue to play my music. I have a PS3 Bluetooth headset that connects to the phone and works perfectly, but I can't listen to music through it.
Is there any way possible you could link me to your device so I could look into it more?

[Q] Nexus 5 Bluetooth and wired headset problems

Hello,
Pardon if this has been answered already, I simply did not find my exact question answered.
I am using my unmodified Nexus 5 (not even rooted), with the latest KitKat (v.4.4.2 build KOT49H) with quite a few wired and wireless headsets and people always complain they cannot hear me. Eventually I got my hands on an old Samsung Galaxy S2 and tried my best bluetooth headset with it: Imagine my surprise, I could hear myself quite clearly even when I was talking really really softly, barely above a whisper. My headset is excellent. My phone is not.
My questions revolve around what to do about it.
Nothing in KitKat allows me to adjust the bluetooth microphone gain, nor does it let me use an equalizer on my microphone. I can adjust the volume of the headset, but this does not do anything to the microphone gain.
So...
Question 1: am I the only person with this problem?
Question 2: what do you people do about it?
Question 3: are there any mods / custom ROMs out there that attempt to fix this problem? Google does not appear to be interested in doing so.
Thanks in advance!
*bump*
Any ideas? I have tried re-pairing my bluetooth headset - no go. I have tried flashing custom ROMs and kernels - no go again. It seems to be a problem with the phone, but I have no idea how to fix it. And Google searches always return other people having this problem. Noone with solutions, though.
Using a wired headset results in even worse results, if that were at all possible.
Has anyone tried to replace the bluetooth stack or driver with something that works?
Thanks!
*bump*
Yesterday I spent quite a few hours tinkering with my phone. I tried every last radio out there for the Nexus 5 and none had any effect on bluetooth microphone levels. Then I tried a few AOSP ROMs: CM11 and Omni. They turned out to be so closely related I might as well have just tried one. None had any effect on bluetooth microphone. Heck if CM11 doesn't do it, there really are no alternatives out there! I tried the FauxAudio tweak, even paid $2 to Faux, which successfully managed to do nothing: app didn't was written badly. Finally, I tried a bunch of volume boost tweaks. That worked, actually. That is, it boosted the wrong volume. Finally, in a moment of true and utter desperation, I opened an ADB shell and edited that mixer file by hand. I then discovered that microphone gain on bluetooth is not controlled there.
I tried all my wired headsets again: Etymotic HF3's microphone produces such an atrocious sound, if I am to rely on it I need to seriously consider becoming a mime. Then there were my Bose QC15 headphones with a remote cable for Android by some off-brand company: that was terrible, the cable is useless. Heck, not even mime lessons can help me there.
Eventually I chanced upon an old microphone cable for my QC15 headphones. Just microphone, no remote. Surprisingly, this one is loud and clear! That after being anything but loud or clear on my old cell phone. Interesting. Unfortunately, it's been out of production for a few years. My working theory is that Bose realized putting a decent microphone on expensive headphones gives people real value, makes them spend money, and that way lies madness. We can't have that, can we. So when that cable starts cutting, so does my use of this cell phone.
I am screwed.
In any case, I will stop bumping my own thread, you guys obviously don't know a solution or there would have been a lively conversation right now. And I am pretty sure there is a moderator or two frowning right now, possibly getting ready to throw an encyclopedia at me. My only hope is that Google is going to do something about that pesky Broadcom driver that doesn't work sometime before the mass exodus to the iPhone. And before my precious microphone cable stops working, or I will be leading the way for that exodus. It's a phone, damnit, if it doesn't work like one it's no good.
Hmmm.... it should be possible to wire a good lavalier mike on a cell phone cable... maybe I can get an op-amp from an old tape recorder to get decent amplification... When attaching a 9V battery on my headphone cable begins to look appealing, we really have a problem.
Yes, if nobody reply you is because no one can help u.
But for what it's worth, i had an Xperia Play for 2 years. Using an Motorola Bluetooth Headset H350 while driving and a MW600 Sony Ericsson Stereo Bluetooth Headset, both never had a problem.
Now from 2013 Christmas both headsets with my new N5: still never a problem and not noticing any low volume or mic. Sorry
same issue

hi,
i am having the same issue with my Nexus 5 in combination with my Logitech H800 Wireless headset (people can`t hear me).
Anybody who did find a solution for this?
Thx

No solution. I tried everything, everything I could think of. I got FauxAudio to work eventually and that did nothing for Bluetooth performance (and it said it wouldn't, but I was desperate).
I returned a lot of high end bluetooth headsets over this issue. Eventually I came upon the Plantronics Voyager Legend. I would like to tell you this really expensive headset works fine, but no - microphone gain is still low, though this time around people can hear me okay. Not great, just okay. I am using that now. It's not perfect, it's far from perfect, but finally usable. Sort of. If I speak loudly.
For what it is worth, the ElementalX kernel improves Bluetooth stability on the N5 quite a bit. Microphone gain is still low, though. Another thing that sometimes helps a little is turning off the multimedia profile on the headset, though why THAT would make a difference is beyond me.
All we can do is wait, watch the Samsung Galaxy S5 get released and wonder if we should switch.

Somebody advised me to download the app "persist"
This is free from the playstore.
Can you try this and let me know this is working for you?

This app controls the bluetooth volume, not the bluetooth gain. The bluetooth volume was never a problem.

Ok,
i am having the problem with my Logitech H800 headset with the nexus 5.
So this is a android kitkiat 4.4 issue?
Or is this problem only on several Nexus 5-devices?

My guess is either the bluetooth baseband or the bluetooth kernel driver used in the N5 is flaky. This is why I think so:
Problem does not exist on my old Samsung Galaxy S2, including when it runs the same nightly of CM11, nor does it exist on my computer or my desk phone. All the headsets I've owned performed admirably there, so the headsets are not directly the cause. From what I've seen no ROM and no kernel out there seem to be making a difference as far as Bluetooth gain is concerned, the problem is persistently there and the same. Best I could tell it's just the N5 with a problem and it's just for the phone profile. I've tried the Bose headset (the worst performer headset with the N5 of the lot) on a colleague's N5 and his phone was just as bad with it as mine. I am not sure if it's a small batch of N5s having a problem, I don't own lots and lots of N5 phones to try on, but I doubt it: with anything digital things are usually all-or-nothing and the N5 has an off-the-shelf Bluetooth chip, which is not unique to the N5. My guess is it's the entire model, but having only tried on 2 N5 phones, this is no more than a guess.
From what I saw online, the entire Nexus line has poor Bluetooth performance, not just the 5, and Google changed the Bluetooth stack with KitKat besides possibly introducing more problems. If you have a non-Nexus phone, the manufacturer most certainly replaced the Bluetooth driver and radio with one of their own, so problem goes away, but the Nexus line does not enjoy such attention.
An interesting thing to try would be for someone to put the LG G2 Bluetooth driver on a N5 kernel and try it out. I don't have the time or the expertise to do that, but there are plenty of people who do. Assuming the G2 does not have problems with bluetooth gain, if the problem still persists it will tell us if it's the N5 baseband or hardware doing it, and noone can help us there if that's the case.
I have this problem too, using my Nexus5 with iphone headsets. Peoples told me in skype and hangouts, that they hear me bad...

That's a different problem. The wired headset problem is easily solvable with FauxAudio and a supported kernel.
This maybe realted to the changes Google made to the core Bluetooth stack as of Android 4.3+ I know they made adjustments for the BLE [low poer Bluetooth devices like pedometers and other senor type crap]. It is BEYOND me as to why Google keeps adding functionality ot the core Bluetooth stack when it is GLARINGLY OBVIOUS they have real problems with Bluetooth as a whole. WHY NOT fix the core issues so Bluetooth is much better at the basics before trying to add functionality or more complex?
I know they complained it would cost a bit for a different newer Bluetooth license but I mean in my personal experience with many different phones Bluetooth is SUPER flaky even at it's best in Android, and does not even work the same way across devices [I have used 3 different Jabra speakerphones on my bosses Galaxy 3 recently and they all worked to varying degrees even though they all use the same version of Bluetooth protocol], but my T989 [Galaxy 2 T-mobile], my parents G2s My bosses older Bionic, My fathers new Droid X, etc. all have random problems. You can usually find one device that works well with a certain phone/ROM, but that can change between ROM versions and devices so it is like you need to go and buy 1 of everything every time there is an update and go crazy finding the ONE that works [and as noted on page 1 with the gentleman using the same Platronics Voyager Platinum as I have it is a super expensive very nice device that worked BEAUTIFULLY in ICS, but now in 4.1 + you can not get more than 1 or 2 words across the mic unless you are YELLING at it like a crazy person on the SAME device].
So all that to say I think it is prolly related to changes Android made in 4.3+ flipped the Bluetooth operability on it's head.
Mic Volume OK with KitKat 4.4.4 and cheap "HB-800" headset
there've been no posts for a while so maybe the problem has gone away with the KitKat updates.
But anyway:-
I have a Nexus 5 and recently bought a cheap generic stereo earbud headset with mic from eBay .... $14.82 Ozzie including delivery to Western Australia.
I've actually asked the other party whether they can hear me (specifically "am I loud enough?") because I read this thread and have been assured that it's all good.
In fact it's a pity the sound quality at MY end isn't better, but that's probably the low quality ear buds rather than electronics / firmware reasons.
Of course, ymmv.
Here's the ebay item title in case anyone wants to look it up or I can pm the item number if it helps.
"Headphones Earphones with MIC 1st Stereo Bluetooth Hands-Free Wireless HV/HB-800"
No, the problem is still there. Reason there are no posts is that no one has a solution. Nothing has changed since March. I am somewhat controlling it with CM11 running on the ElementalX kernel. Without this kernel Bluetooth performance is unbearable. With it it is barely adequate.
It's funny that a cheap headset would work okay while multiple top-of-the-line everything-but-the-kitchen-sink models like the Plantronics Voyager Pro would still be having problems.
I was seriously considering getting the OnePlus One, the Nexus 6 and even the iPhone 6 hoping the issue would finally be fixed. It's ridiculous that a phone commonly accepted as the measuring stick of the Android world would be having problems with simple tasks like driving a bluetooth headset. *very disappointed*
Me too. Two days with my new N5 and when I use my Sony SBH20 people hear me bad... With my N4 no problem. Its annoying! Ive to speak with headset because Ive problems with my left arm and legs, I only have the right to hold the phone, I cant do anyhing more and when I walk I need that arm to hold my cane.
I dont see a real solution, I will have to return the N5

[Q] One plus one audio popping issue

Hey guys, I don't know if this has been addressed but I just bought my one plus and I've been listening to Spotify in the car. I'm a huge commuter and listening to music is a huge part of my daily work week. What I notice is random audio blurring and bleeping and audio popping that I'm not sure if it's a defect in my device or is a software issue. It seems that the audio is screeching into brief blurbs and it causes high frequency random blurbs in the music. It's hard for me to explain. Does anyone else notice this? Is this only with Spotify? Or is this something that my phones hardware? I'm using an Aux cable that's worked perfectly with my iPhone in the past. I'm running cm12 nighty 2/21 with AK kernel under volted. Any help is greatly appreciated. Thank you. :crying:
Bump for help
There are several threads already discussing this here in the OnePlus One section, have a look around and you'll find them.
