I haven't gotten my device yet (in the mail), but I've heard there is a BT headset bug which causes the person on the other line to have difficulty hearing you.
Is this true? Is there any fix?
i havent recieved my phone either yet but havent heard anything about the bluetooth but if your interested in a awesome bluetooth def look at a jawbone the jawbone i have is freakin amazing lol
I have a mogul and a tytn and a jawbone.
I have seen other posts (hofo, ppcgeeks, etc) that say there are major problems with bluetooth but I have yet to see them. I did use the bt fixes that I applied to my tytn to the mogul and have not had any problems. Jawbone picks up the request just fine.
Brad
There is a 5 pg thread over on ppcgeeks where people have been sounding off, but it doesn't look like there is a fix. I personally have a Motorola HS820 which has worked fine with my old CDMA 6600 that apparently sounds terrible on the other end.
Doesn't look like the ROM upgrade addressed the BT issues either...
The Jawbone sucks. Total waste of money. Overactive DSP and the worst wind noise of any BT headset. BT might be fixed in a future ROM update.
from what i've heard, the new sprint rom 2.09.xxx fixes the BT issues. I haven't gotten around to pairing my headset with it since the rom update, but I will at some point or another and let u know if it has made any difference.
I can only speak for my experience.
I am using the 2.0.9651.3 ROM on the mogul with the same BT fixes that I have used on my Tytn since they were made available ( BT Voice Command Fix from XCSdM and reg tweaks) and am not having any of the issues mentioned in the thread at ppcgeeks. My phone also came with that ROM from Sprint.
I have also used about 12 different BT headsets from Nokia, Jabra, Motorola, and others and the Jawbone has been the best so far at reducing outside noise/interferance.
Again, just my experience.
Very glad to hear that Park City!

You heard wrong. The ROM update does nothing except add Sprint's Music Store.
BT issues post-ROM update
I may be the unlucky one here, with a different story, but no one complained about my BT conversations prior to the update. Now, I've been told that my headset was "cutting out" today, so I had to hang up and turn off blue tooth to finish my conversation. May be coincidence that I didn't have problems before as the device is only two weeks old to me, but the ROM update definitely did not address BT as far as I can see. This BT reminds me of my Treo 700p....

The only fix is to get a different phone with BT that works.
had the phone a couple of days now... BT has been alright for me, although I don't use it for more than a few minutes of talking at a time!
Does anybody know how to improve sound quality for playing music over A2DP profile with Parrot handsfree? On Rhodium i applied some tweaks for quality improve and it was clear and nice to listen, but Leo is not so nice to hear
Thx a lot
I had to tweak my diamond too, looked for tweaks on the HD2 but couldnt find them, but the sound quality is way better on my HD2. I dont think it needs the tweeks tbh.
If i take both, TP2 and HD2 to my car, let play the same song and im switching between HTC's then has got TP2 much more clear and brilliant sound, without any quiet cracklings from tweeter speaker like it is on HD2 :-(
Same problem here, sound quality for a2dp is not what it should be. I tried adding the LineSpeed registry setting, it did improve the overall quality, but did not remove the cracking noise - and in my case I still have frequent skipping and gaps in the audio playback. Have not yet had a reply for Tech Support, and if/when I do, I don't think it'll be a very intelligable one...
Yop, i think too, that the answer will be unusable, or maybe they tell you that u should do a Hard rst :-D
First time i connected it to HF and let music play i thought that is a bad quality song, but it isn't :-(
Anyone idea?
I know there are some settings to definately improve the sound of A2DP. I've added them on my previous HD, and worked perfectly after that! I just found some things you might try (I just applied them myself as well, but havent tested them yet; I'm almost sure they'll work):
http://forum.xda-developers.com/showthread.php?t=308752&highlight=A2DP+settings+bitpool
If I'll find the previost post which I applied in the past on my HD, I'll let you know. If the one I just posted will work, I'll let you know as well of course, because the litteral and figural crappy sound of A2DP is something I hate as well...
Edit:
Take a look at those settings as well from J-A-J-O at page 6:
http://forum.xda-developers.com/showthread.php?p=1677577#post1677577
Again, I don't know exactly if it were those settings, but they sound familiar to me. I'm also busy trying to get the best sound quality via bluetooth out of my HD2

The XDA tweaks are rubbish and do not work. I currently have a call out with HTC.
I have removed all reg tweaks from my HTC and now can get A2DP working on my parrot ONLY in the following situation:-
(1) Reboot HD2 (hold end key and select off. then switch on)
(2) Allow to connect to Parrott (will connect handsfree first)
(3) Open bluetooth from settings and select stereo audio and select connect.
(4) select handsfree and select disconnect.
(5) Press PLAY on the parrott kit
By doing this I get no skipping at all and the quality is good. I have no tweaks running.
This is obv crap and is why I have been speaking to HTC all week.
Steps 1-5 have to be strictly followed for this to work.
The BT tweaks mentioned on this forum do not work. They only appear to work as you have rebooted. After using the HD2 for a while and then connecting A2DP, skipping will occur again.
Try steps above and it will work.
Interesting! I'll try that on mine. Greenfrog all of those links and bitpool settings relate to the Microsoft Bluetooth stack. However the HD2 uses the Widcomm stack so those registry settings can't be made.
I too am fed up of the bluetooth sound quality. How can they assume we'll be happy with this mediocre sound?! I can't see why with a 1Ghz processor it skips.
Have you guys tried the A2DP with the latest 1.61 ROM? I'm still on 1.43....
When I find my 'goldcard' that I made I'll try it on 1.61 and let you know
We'll get there in the end....this is really my only bugbear with the HD2, so it would be good to get it fixed!!!
There got to be a way!
I, too, am really p***ed off by the bad audio quality i get using stereo blutooth. It's really an issue with the HTC HD2 and apparently no pro reviews pointed it out!!! I use it with the sony DR-50 which are one the best A2DP headphones out there, but the sound is horrible Please help...
I'm too suffering from the A2DP situation...
The Linespeed registry hack helps me on some devices ( HKML\Software\Widcomm\Plugins\AV add DWORD Linespeed with value between 64 and 512, the higher the better sound but higher probabilty for skipping).
With Linespeed = 320 sound is great and I have no skipping with a Sony DR-BT160AS. But: My Motorola S9 badly skips unless I have it very close to the HD2. Linespeed = 256 is working ok with both devices...
BUT:
I also have a blueLino A2DP Receiver which has a bad quality on both settings, at least on some songs. That's really disturbing.
Just a quick update, I've just flashed to 1.61 and it makes no difference. Default A2DP sound quality is unacceptable. Grr

-----------------------------------------------------
Well, first I have to say I don't have the 'skipping' issue at all. I have my HD2 connected via bluetooth to my Pioneer DEH-P7100BT car radio. I have a clear connection when calling, but when playing music via bluetooth, I have the 'hissing' issue.
Next is that I have to admit that when I changed the settings according to my previous solution, did work a little, but not as it supposed to. When I had my previous Touch HD if found a link which worked perferctly for me! When I changed to those settings, the hissing were gone completely and the sound quality improved to CD level. Although, I'm still searching those ones again for my HD2 at the moment....
So, conclusion this far is that it totally depends on the hardware which you are connected to as well.

@Greenfrog:
I guess the bitpool settings which worked well on my HD as well, only work when using the MS Bluetooth stack. The HD2 uses the WIDCOMM Bluetooth stack, I haven't found a noticable difference.
The LineSpeed registry setting does improve overall audio quality, but I still have skipping and playback gaps. Very poor performance for the performance beast the HD2 is. I urge everyone to report this to HTC (I did) - this is really unacceptable.
I will also report this to HTC. I am so frustrated by it tbh
As Moses posted...I had linespeed set up on my TP2 and the sound was great, but now i have no time to test it now, can someone other test regitry key?
Bluetooth settings
Can be found here HKLM\Software\WIDCOMM\
A2DP Tweak Provided by R_phAn (Please note this will not work with all devices)
As we know from the past, each device has it's own preferences and capabilities (So you'll have to play around)
Managed to improve soundquality by adding DWORD 'LineSpeed' to HKLM\Software\WIDCOMM\Plugin\AV\ with a value of 320.
it is posted here for TouchPro2: http://forum.xda-developers.com/showthread.php?t=524655
Edit: I tryied it tomorrow morning and it is still the horrible quality, poor music quality and during the call skipping :-/

Okay, thanks a lot for this update! I was really unaware about the different stack, so I don't have to look further for the the previous links anymore... I'll try to add linespeed as well to see if it works with my Pioneer car radio. I hope it will...
There should be an answer for sure for this issue. I also cannot understand why it have to be this difficult. The previous solution did work very well. Why have they changed to the other stack anyway? Does someone know that?
I'm running the 1.48 ROM btw.
GreenFrog
I found one thing, i'm using SPB Radio for online streaming, when im listening in my car streamed radio then the sound quality is excelent...? How is that possible?
That's a very good question.
I experimented a bit with different quality settings during mp3 encoding. I found out that there indeed is a connection between the quality settings of the mp3 file and the badness of the sound quality, at least to a specific degree.
The most important setting seemed to be the stereo setting. If I set a song to "Joint Stereo" its by far better than normal stereo, although not perfect, yet. That's very confusing.
Do you know the settings of the radio channels you can stream with good quality? Maybe that would be worth a test.
--Update--
So I had a predictably useless response from HTC. Namely 'have you tried unpairing and repairing' and 'your device may not be fully compatible, please check our website for a list of compatible devices'.
Useless indeed. Their compatible devices amount to 3 items! The phone is either A2DP or it isn't. There are no compatibility options - it's happening to us all.
So, I haven't mustered up the energy to continue onto the next pointless exchange of basic trial and error possibilities. No doubt their next reply will be "have you tried rebooting the phone"...
Anyway, I digress. I noticed something today. I put on a new album to my SD card and out of nowhere the skipping was worse than ever. Audiomanager is always on the lookout for new songs as you may have realised. When you have music playing, a small circle rotates to show the player is searching. During searches whether or not you've introduced new mp3's to your device, it always makes the skipping far worse. When my circle had come to a stop, then the audio was fine....with very rare pauses and skips.
Still there but much less obvious.
Well that's my latest update and I will continue my investigation. I wonder if this skipping occurs in other music programs? ie wmp or pocket player? Has anyone tried?
Great work, guys. Nice to see a lot of people looking for a solution. I REALLY want to get this A2DP thing working right, it is bugging me a lot, and I'd like it to be fixed when I'm going on vacation (I'll be driving to two straight days, and would love to listen to my own music then). That'll be in about six weeks, so there's still some time left.
I'll try SPB radio myself, see if that causes the same amount of skipping. It could be that it is not the BT link causing the skipping and pauzes, but the audiomanager itself. That would be a bummer, because fixing that is probably way beyond what we can do here, and we'll have to hope for a HTC fix or a custom rom with an older and better working version of the audiomanager.
In my search for possible solutions, I found the priority of the A2DP can be altered. I've added the reg Dword value "Priority256" to HKLM/Drivers/BuiltIn/BtA2dpSnd, with different values. If the value is too high (150+), nothing changes. Set it too low - I tried 60 - and BlueTooth fails to start altogether. I've now set it 149, and it seemed to work, but haven't done extensive testing to see if the skips/pauzes don't return. Will get back on that.

I've tried PocketMusic, qualitywise no difference. I don't remember if it had the same skipping / pauzes problem, but the problem for me was it doesn't work with the AVRCP, so I can't play/pauze/ff/rew with my remote, and having to use the screen while driving is a pain - I've mounted my device quite high. I was really hoping to use the inbuilt musicplayer
All,
Does anybody have any fixes regarding the sound quality when using Bluetooth A2DP protocol? I use my Evo to mate with a Bluetooth receiver so I can listen to Rhapsody over my home stereo. The sound quality is flat. The high frequencies are not present. It sounds like a bad quality MP3. I know that its the A2DP causing the quality issue as directly connection (through 3.5 jack) is awsome.
The Apple 3GS A2DP sound quality was awsome. I am not sure why the Evo is not sounding good. Any help would be most appreciated.
Thanks,
Lance
use the cyanogen rom--this uses a bitpool of 53 giving you the best bluetooth quality possible. the stock/sprint/htc bluetooth drivers are set for a bitpool of 32
Is there any other ROM that has the bit pool set to 53?
Lance
Nope all Sense roms use HTC's ****ty low bitpool setting. This is why I'm running CM as well it's the only rom I can A2DP to my Sony Head unit and get good audio. I attempted to contact HTC about this issue here's the juicy details
Here's my initial question
I have terrible static when streaming music over A2DP on my HTC EVO to my sony mex-bt2800 car radio. If I use CyanogenMod 6.0 which uses a open source bluetooth stack my A2DP is crystal clear to my radio. I have used logcat to look at whats going on I dont know if its a bitrate problem or a bitpool problem or if my radio isn't in your acoustic database.

Here's the response I received
Although the android software has been updated to be more compatible with Bluetooth headsets and car kits. Most of the time a Bluetooth manufacturer will have a list on there website stating devices they have found compatible, but this is not always the case. From the information on your issue it seems that your device is simply not fully compatible. The only thing we would be able to recommend would be to try another headset.
Then my response back
I would like an Engineer to read my question if possible since I don't think you fully grasp what I'm saying here. First My EVO's Bluetooth A2DP WORKS 100% clearly when using a Open Source ROM which implements Bluez Bluetooth stack http://www.bluez.org/
When I run your Sense UI ROM the Stock ROM you release which uses your own proprietary Bluetooth Stack I get static in the background so you cant really say its my phone now can you? Its your implementation that's not working properly. I'm not about to try every car stereo till I find one that works with the EVO when I know my stereo can work perfectly with my phone when using a properly coded open source Bluetooth stack.
Here is some extra info from a logcat that shows how your Bluetooth makes a connection through A2DP and what I believe is too low of a bitrate or bitpool setting

PLEASE DON'T GIVE ME A ANSWER THAT YOU JUST READ FROM A SCRIPT.

I await your educated answer.

Well I commend you for trying. This is something that makes me want to tear my hair out so I would love to see this resolved as well.
good on ya mate.
anyone know how to get another bluetooth stack on stock rooted 2.2?
I asked Flipz a while ago but I don't think he's looking into it. I also asked Netarchy he said he would look into it sometime but that i shouldn't hold my breath since he hadn't even looked at the code yet. HTC has released the source for their Bluez implementation so all we need is a dev willing to look into adjusting the bitpool setting.
This is a HUGE problem. I am flashing CM6 right now. HTC I am very disappointed with you..
The cyanogen rom also has great dsp equalizer
CyanogenMod will also make you a tropical island than transform your EVO into a jet plane and take you there ;-)
But in all seriousness, yeah, CM6 has BT fixed. One of my friends nagged Cyanogen about it last month, and he patched it right away.
I wish somebody could help us by increasing the bitpool on the Bluetooth driver. The Evo would be so much more enjoyable (for me at least) if the sound quality was better thru A2DP.

Just an update today I got a call from HTC customer service since i gave a poor review of my experience on a survey they sent me. Talked in great detail about our problem with the Bluetooth stack told him about the bitpool setting how its 53 on CM and 35 on there roms. So hopefully on the next update well get a fix for the Stock Sense UI rom.
^^LMAO!!! dont blv the hype
I read that the CM6 ROM has this issue fixed. I have also read reports that the ROM email client doesn't support word wrapping (which I really do need). Can anybody confirm this?
Also,
Can anybody in ROM land please create a patch or an update to their ROM which increases the Bitpool to 53? I understand that the Bluetooth driver code has been released.

Hello,
I have the few following minor issues with my now one month old streak which I hope there are solutions for:
Bluetooth headsets/speakerphones pair, however, voice dialing application always crashes
Camera application freezes/crashes and causes the phone to reset about half or more of the time
GPS (google maps nav) is constantly searching for signal even though I can see my exact/precise location
I can definitely provide more details around each of these issues. My understanding is that each of these problems is out there after some googling generally and on this forum. I have been unable to find anything with respect to a solution.
In terms of my phone/software:
Android 2.2, Build #: 12332, Kernel - 2.6.32.9-perf
Thanks and your help is much appreciated!
Get in touch with your supplier, it sounds like the unit has some hardware fault that you're not going to ba able to fix.
Thanks for your reply. I have seen that the Camera issue and especially the Bluetooth issue are pretty common ones. I tried formatting via the menu/privacy options. Will hard-resetting have any bearing on this? I am hopeful it is software related?
Im having a problem with my gps as well. Im on 318 with perf mod. It wont lock. Hrmmm wonder if this is a common problem.

cbaronne has posted a set of compiled binaries to change the default bitrate of the Bluetooth SBC codec to increase A2DP audio quality on the Nexus 4 over on this thread. It seems that the 2013 Nexus 7 suffers from the same issues, but can also be fixed with the same binaries.
I've very lightly modified itlnstln's update script to work on the Nexus 7 and have tested these files as flashable under TWRP. The binaries in the flo-4.3-BTFix-googledefault.zip file are from the ParanoidAndroid 3.94 ROM (which I would highly recommend) should you experience troubles with your Bluetooth devices.
I would recommend trying the 328kbps version first, and would expect it to provide the best quality in most situations since it matches the sampling rate of most MP3 files. Most Bluetooth stacks for other devices have 328 as the maximum quality. Of course, test with your devices and ears.
For device testing, I've used it to great success with a BlackBerry Music Gateway (still stuck at low volume, but that's an AVRCP volume control issue) and a Philips AEA2000/37 Bluetooth receiver. I also have an eBay/Chinese receiver which identifies itself as DMZmusic where this change causes continuous popping noises from both my Nexus 4 and Nexus 7. That device is perfectly fine when paired with my other devices that stream at full quality with A2DP SBC (BlackBerry Playbook, WP7 phone, and Windows PC using the Toshiba stack), so clearly Google still has some work to do. Until then, hopefully these files prove to be useful.

Yes, just flash with TWRP. Note that this only affects A2DP Bluetooth audio (ie: wireless headphones and stereo receivers) in situations where it sounds like Internet radio from the year 2001 and won't do a thing for the static noise when using the onboard speakers at low volume.
328K did seem to help with Netflix + BT but it certainly wasnt perfect. Its rather disappointing that such a powerful tablet cant even BT + netflix properly.
Thanks much for sharing.
Aren't any Android Tablets/Phones out there which support BT-MP3/AAC Codec? Maybe those can be ported to Nexus devices?

I don't think you can blame the Nexus 7. I reverted to the previous version of the netflix app and the audio is fine. It appears netflix broke something with the latest update.

cbaronne has posted a set of compiled binaries to change the default bitrate of the Bluetooth SBC codec to increase A2DP audio quality on the Nexus 4 over on this thread. It seems that the 2013 Nexus 7 suffers from the same issues, but can also be fixed with the same binaries.
I've very lightly modified itlnstln's update script to work on the Nexus 7 and have tested these files as flashable under TWRP. The binaries in the flo-4.3-BTFix-googledefault.zip file are from the ParanoidAndroid 3.94 ROM (which I would highly recommend) should you experience troubles with your Bluetooth devices.
I would recommend trying the 328kbps version first, and would expect it to provide the best quality in most situations since it matches the sampling rate of most MP3 files. Most Bluetooth stacks for other devices have 328 as the maximum quality. Of course, test with your devices and ears.
For device testing, I've used it to great success with a BlackBerry Music Gateway (still stuck at low volume, but that's an AVRCP volume control issue) and a Philips AEA2000/37 Bluetooth receiver. I also have an eBay/Chinese receiver which identifies itself as DMZmusic where this change causes continuous popping noises from both my Nexus 4 and Nexus 7. That device is perfectly fine when paired with my other devices that stream at full quality with A2DP SBC (BlackBerry Playbook, WP7 phone, and Windows PC using the Toshiba stack), so clearly Google still has some work to do. Until then, hopefully these files prove to be useful.

I don't know if this is related to the problem of BT keyboards working properly (interference on the 2.4 Ghz band between WiFi and BT), but if it is, would you know how to fix that problem as well? Only reason I ask is that I was under the impression that BT audio also suffered from the interference issue, and would especially make sense if paired up with netflix streaming (which would be sending data over WiFi simultaneously).

I haven't dealt with that issue specifically on the Nexus 7, but I have had nothing but terrible luck with most Bluetooth HID devices for PCs and now just recommend using sets from Logitech or Microsoft with proprietary RF USB dongles. Apple's devices tend to work OK though. As for interference, I have no trouble streaming BT audio while also pulling HD video over my 2.4GHz WLAN, but then again I'm not in a very RF saturated area and also have automatic channel hopping disabled on my WiFi AP. If you're in a highrise or something like that, the only possible solution is going to be to get your WLAN onto 5.8GHz to try and free up some spectrum.
I don't think I've heard of any Android devices that do MP3 or AAC BT audio, but there are quite a few that can do AptX. As far as I know, only the manufacturer ROMs provide the codecs for this (ie: flashing CyanogenMod to an SGSIII will kill AptX), and receiver compatibility is pretty low. It's a shame that there are so many cooks in the Bluetooth kitchen that we end up with this metaphorical beef and Cheetos stew.

Ill have to try that. Nonetheless there are some bt issues relating to 4.3. I was attempting to watch a youtube via bt headphones and my vz hotspot on my SGS3 and it stuttered along, but when I turned off bluetooth it streamed fine. This is rather aggravating.

Thanks posting your fix. I just reverted to a previous version of netflix and now I have absolutely no audio issues over bluetooth.

:good: Huge thank you to OP. Ever since I got my nexus 4, it always had crappy bluetooth audio playback. For a while I wondered if my speakers in the car were damaged also but I tried your fixed and it worked flawlessly. Crystal clear and rich sound now. This is confirmed working on the latest stock nexus 4 jwr66y

You know, I downloaded a Beats Audio APK and that did the trick. Just google BeatsAudio07.02.zip and the first link will where you can download it. I noticed a big difference on my N7 I use at home and definitely the N7 I have installed in my car. The sound thru my Infinity System sounds like crap. Once I downloaded and flashed this zip, it was a huge improvement. :good:
Just got a netflix update last night (3.0.1 build 1016,) fixes the bt issues I had with it =]
Can't update
Does anyone have the default audio.a2dp.default.so, after applying this fix I can no longer OTA.

Error: Unfortunately, Bluetooth share has stopped
Hi Guys, I'm new to N7 and first thing I wanted to do is to upgrade BT audio q. After causing endless bootloop (X), I had to restore device to factory settings using Nexus Root Toolkit v 1.7.8 and loading Android 4.4.0 - Build: KRT16S. Only after that, I tried again to flash "flo-4.3-BTFix-328kbps-2013-08-18.zip" and everything looked ok until boot when there was a pop up message with an error: "Unfortunately, Bluetooth share has stopped". Same with other zip (345kbps). Any idea where might be the problem?
EDIT: Obviously I was trying to use 4.3 fix for 4.4. build When I realized it, I loaded again 4.3 system, flashed zip and seems to be ok now!
So anyway @random_n, could you please update this fix so it would work for 4.4 as well. It would be greatly appreciated!
Has anyone found a kitkat audio fix yet? I justvtried my BT headphones with my n7, and the sound is ungodly bad compared to my galaxy s3.
Since the tablet gets longer battery life, I'd prefer to use it for my wireless audio instead of the s3.
