ok..thanks..
I did the modification and sound is stereo... but quality is really poor, as if sounds comes out at 22khz and not 44khz .... Is use I-tech R35 or S38 which are working almost good wiyh HP6515 ....
Does someone have any idea what happens
Add some more:
HKLM/Software/Microsoft/Bluetooth/A2DP/Settings/BitPool - from 30 change to 48
HKLM/Software/Microsoft/Bluetooth/A2DP/Settings/MaxSupportedBitPool - from 30 change to 58
Thank you, .... sound is much better now .... just now, I am missing the naviplay where the trebles where much better than with itech R35 or S38, I have at the moment....

thanks...it's more stereo now but now i'm experiencing"hissing"sound which never
before. can i adjust it to any other value? is there any combination i should follow?
thanks..
I found that "hissing" is dependant on the headset used.
My plantronics have almost no hiss, while my cheap i-tech things have lots.
Anybody else have the option to compare different headsets?

I use Samsung H200 for Handsfree - it has a sligt his when it initially connects which disappears as soon as the call is connected.
My Plantronics 590 headset has no hiss and sound absolutely clear and crisp.
Maybe the right placeereo head set and I paired it with my 7500 as a stereo head set
I posted this thread somewhere else,but it seems to me that people here understand the kind of problem I have
I use a motorola s9 st

And your problem is?
Oooooooops...
I didn't realize the whole message was missing,it is like when the celular line fails and you keep on talking...
Well so I have this magnificient Motorola headset S9 and I sucessfully paired it as a Hanfree and a Stereo headset
Everything is working perfect,except the fact that when I activate the voice tag (which usually with oter BT headset works perfectly) I cannot hear the beep telling me to say the voice tag and also I cant hear the confirmation (that the PDA understood what I said)
The voice tag DO work and if I am lucky it dials what I say but I can know only when someone pickup from the other side ....
when i dis-pair the stereo headset,it is working again.
I know it is not the most horrible problem reported in this forum,but if anyone can help....
How to play music via bluetooth device
I've got a set of Harman/kardon Soundstick II speakers and i wan't to play music wirelessly from my laptop (HP Pavilion dv6000 series) onto it i.e I don't wanna plug the speakers directly into the laptop.
I bought the Sony HWSBTA2W Bluetooth Transmitter/Receiver and have managed to connect/link it to my laptop. The problem is however, how do you get a music program such as Windows Media Player to play music via the Sony device. I have managed to play music from my Nokia 6600 phone through the device successfully but am unable to play music from my laptop.The Sony device appears as a bluetooth headset in my list of bluetooth devices, but does not appear as a speaker on my laptop.
And oh yes, my laptop is wireless and bluetooth enabled.
Or Is there another wireless dongle or bluetooth item of some kind that i can plug my speakers into and will stream the music down from my laptop.

Hi,
i have Galaxy S with I9000XWJM5 and have some strange problem when listening to music in my car. I connect phone with AUX cable to my car radio.
The problem is that playback have glitches every few seconds, it's 4-6 glitches per minute of playback. I don't know how to exactly explain that glitch. It looks like you quickly disconnect/connect jack to phone. I've had iPhone, Samsung Wave and several other mp3 players connected that way in my car and none of them had these kind of problems. I've also checked jack and cable and everything is fine. Connection to phone is also fine during testing. Do you think it's because software? Or maybe it's bad checking for AUX signal in the phone?
I'd say most likely software, but I'd be guessing.. There isn't really any way of knowing.. Is this with FLAC?
I'll try change something in my car audio. I think it might be caused by changes of inpedancy.
I don't get glitches in my car AUX unless the files themselves glitch and stutter (which they do with FLAC files). I would check to see if you have any EQ settings in your car stereo on, that is the culprit sometimes.
How is your playback with headphones/earphones? If you don't have same problems with them then it's likely something with the mini cable or the car stereo. If not, then likely something with the phone hardware/software.
Playback with headphones is 100% good (sometimes excluding FLAC playback as you said). I'll try changing EQ in car and if this don't help i'll try changing inpedance and write here what happened.
have you considered using bluetooth in car to stream audio from the phone instead of AUX cable?

I was thinking about it but my car radio don't have bluetooth and I won't change it because it's pretty high end Blaupunkt and I love how it sounds.
Second thing is that a2dp has lower quality that regular aux.

I would also make sure it's not the data/phone connection somehow getting in the way of music playback. Try it on the airplane mode and see if you are getting the same glitches.

i think i know what you mean.
you are refering to those annoying sounds when a call is about to coming, or when a data transfer is in progress, or whenever your phone switches from one tower to another tower
you get the ddddddd...d.d.d.d.dd..ddd.d.d.d.d.d.d.dddd... sound on the speakers, if your phone is connected to the stereo via 3.5
that's one of the reason why i switched to BT in the car.
I've checked line out with amplifier in my house and it's working 100% fine. So i have to check AUX in my car.
Hi guys
i read xda so much, but i don't write as well
i have a big issue with my galaxy s 2
i use a bt car stereo, with a2dp and avrcp support
i used to stream all my music collection from my iphone4
now i got my sgs2 and i love it... but
the audio stream looks "limited"
it seems a bandwidth issue, or i don't know a quality issue
with iphone4 i streamed at full quality, now the sgs2 sounds a lot worst
other than that, i have to disable wifi because if on, the music is choppy and skips a lot
with wifi off, the stream goes well, but it sound bad...
sorry for my not so perfect english... i hope there is a way to improve sound quality because i "live" with a2dp on in my car...
That's strange. My a2dp stream actually sound better from sgs2 than it does from my ipod touch 2nd gen, iphone or my computer (bluez).
Receiver is a belkin stereo a2dp receiver.
Are you sure that it's not in handsfree mode? Long press the a2dp device in bluetooth settings and there should be an option to select it to be a media device, make sure it's checked.
thanks for the reply gvoima, no it's in media device mode
i think the problem is the bitpool
i've got the same problem of this guy: http://forum.xda-developers.com/showthread.php?t=708685
there is an mp3 sample of the problem in the first page

I got a belkin stereo receiver as well, but it sounds bad and choppy, just like the topic starter described. Though still compressed (this is a known issue for A2DP due to bandwidth limitations) songs sounds much better from my Nokia E52 work phone.

The "but my (insert phone) worked better" isn't really valid. For as many people who make that statement there are an equal number who are shocked that the SGS2 works where other phones haven't. This is kind of like the Wi-Fi issue. When two pieces of equipment don't interact well you can't just blame one of them.
In my car and on my Yamaha YSP-4000 the SGS2's Bluetooth works better than any phone I've used. That includes the HD2, G2, and G2X. The sound is much more defined and headset controls (random and repeat) show available for the first time. The SGS2 also feeds track info to the car which none of the others did.
Bluetooth connections and sound quality are always a big YMMV.
My Sony MW600 sound great, I use to have a Motorola Defy , and it use to have an "Enhanced Stereo" option in the blue-tooth menu, the Samsung S2 does not have this option.
@BarryH,
Oh I know, I not blaming the SGS2. I only think the SGS2 out sound to it's output module which is somehow less suitable for the kind of compression, maybe set by the Belkin module. Actually I'm currious if there would be ways to change the way the SGS2 sends sound signals via A2DP

LG's implementation of Bluetooth drove G2X owners crazy. Check out this thread from the G2X forum...
http://forum.xda-developers.com/showthread.php?t=1117769
Maybe it will help. The only other solution for the G2X was installing an AOSP ROM.
Well, I tried it (Bluetooth Fix Repair), but off-course that tool is for a problem the SGS2 does not have.
From the tinkering I've done now I know.
- Having MusicFX installed does not make a difference
- Video players running ffmpeg codec do also not make much difference in sound quality
- The -type- of file does make a difference, i.e. low bitrate files play better
This makes me think, is there a music program which can resample/recode music before playing. I'd rather have software do that than A2DP do it badly, or is mono output (other than all the tools enabling playback on mono headsets which is for pre-A2DP headsets and thus something else) possible?
Edit /system/etc/bluetooth/audio.conf
Uncomment "Master" option and set it to "True".
Uncomment "MaxConnections" and set it to 3.
Most Android devices have this file configured poorly by default, those 2 settings should help though.
I'd suggest also enabling HFP and AutoConnect.
Great! That definitly reduced creaking/noises and even the occasional stuttering music!
Since you seem to know your stuff, would there be a way to send a mono signal to (only) the A2DP stack and would this decrease the 'tin can' effect? I'd rather have better upper tones than stereo.

Thanks for the suggestions...going to try this and see if the sound quality improves in my car stereo.
Till now the best A2dp sound quality was on my Nexus S, but that was with the help of custom rom development and vodoo sound. Worst was the g2x.

Ok guys, I think I might have... accidentily... run into a phenonemon.
I tested my phone on a Creative D100 wireless speaker it it went great, no tin can sound, no hickups.
This proved to me that there had to be something wrong. Now when I was posting here earlier I was listening a lot to music and at a certain moment I thought... wait I'm not hearing a tin-can sound anymore. However, later on while testing I heard it again so I thought I imagined it.
Powering off the phone and powering on again I was able to create this again. No tin can sound... however a lot of hickups (as if a lot of data had to be sent and it didn't quite fit). I made a call to my work phone (sound on the handset) to test and then the tin can sound was there again, no hick ups anymore though. Strangely enough a haven't been able to replicate the 'no tin can sound but hickup situation' though by powering off and on again. Tried after playing on the Belkin on the D100 again and no problems at all, great sound and no hickups whatsoever.
It appears to be a bigger issue with android connected to the bitpool setting the bluetooth receiver desires...
http://forum.xda-developers.com/showthread.php?p=14944891#post14944891
Let's hope the upcoming Cynogen can fix this issue.
I too felt that the A2DP sound quality on the Nokia BH103 is crap as compared to my Nokia 5800 (sounded even better than stock wired headset). It also uses a lot more battery, I find mediaserver using a lot of battery.
How do we escalate this to Samsung?

Hi All,
I have a 16GB TF .. and it's been very good so far. However, I'm having an issue that I think is probably simple .. but google & xda searches don't find anyone else with the same issue.
I want to use Skype over the tablet, but with a bluetooth headset. Using the TF with just the internal mic & speakers is pretty speakerphon-ish .. and I'd like to use a headset.
I have a couple of BT headsets (one of them 2.1 w/ EDR), and I can pair any / all of them to the TF. Problem is, the audio doesn't come through over the head set, and I don't know how to force it to.
The TF (now running 3.1) acknowledges that the headset is connected (to phone audio it says) .. but the only options in the configuration is to remove it.
What am I missing? I see reviews all over the place where folks are using the tablet to play movies in the car, and piping the audio out via BT? I think I must be missing a config step .. but can't find it.
Thanks for your help.
Im kind of in the same boat but I dont think honeycomb has a "phone audio" functionality. Only "media audio," which is what you would use when piping audio to external speakers.
its the same on the phone, those headsets only connect to mono phone audio so if I was playing a movie or music its silent. So for right now I think you are stuck until they figure out how to make specific apps recognize the phone audio device.
Makes some sense .. so it knows there's a "phone audio" aspect to things out there, but we don't have any way to force the Skype audio to be phone audio and not media.
So if I had a stereo headset, would the system work with it and pipe the audio out since it would recognize it as a media audio system?
Where does the mic fit in all of this?
I have a BT combination headset/headphones which I paired with the Transformer, and from testing it I can say the following:
1. The transformer paris with the device and recognizes both the "handsfree" and "media" profiles that the headphones support.
2. The "media" profile (also called A2DP, stereo bluetooth, etc) works fine. I have listened to music in stereo though them and all of the controls like play/pause and previous/next work properly. If you want to listen to movies, music, or whatever else you should be fine.
3. I can hear Skype through the headphones, but testing revealed that Skype is using the Transformer's build in microphone rather than the one in my headphoens. It also doesn't respond to the call button. Thus, it seems to be using the "media" profile to deliver sound.
So, even though the Transformer can clearly recognize handsfree profile, it either isn't passing it to apps or Skype isn't asking for it.
It looks like as long as you plan to be Skyping with the tablet infront of you, you can get almost the same functionality of a handsfree/headset by using a BT headphones instead. As long as you don't plan to leave the tablet in one room and talk in another you should be fine.
hey so i tried Super BT Mono Free Trial and it actually worked. thought it was Froyo only and reportedly broken with gingerbread.
using Samsung WEP450 paired "handsfree" profile, turned on Super BT Mono and to my surprise audio from music player routed to the BT headset. sound is crappy, and so far can't get audio from BeyondPod to the BT headset.
rooted 8.4.4.11 with netformer 1.5 OC 1.6 ghz and juwe11 ram profile.

try jabra... coz jabra headset supports a2dp i had the same issues until i bought a jabra

Hi Guys.
I've seen a number of posts on this subject so here's my story and my experience thus far.
I've been using an iPhone 7 since it came out. I've been very happy playing music in my car (Fiesta with SYNC2 system) all this time. My significant other has been using an S8 for some time, and her music always sounded 'crackly' (for lack of a better word) in the car. I thought this was just her Spotify or something.
2 Days ago I bought my own S8 and I had exactly the same issue.
Now from some research I've been able to deduce that this is down to the Bluetooth Codec the phone uses. I changed mine to aptX yesterday and the music quality was great. Didn't sound like a 200KB MP3 downloaded in the early 2000's anymore.
However...
Last night I had to reboot my phone for reasons, and the developer options reset completely, which I believe is normal behavior. But now I can't set my Bluetooth Codec anymore? I change it, the moment I close the menu, it reverts back to SBC. I tried this with Bluetooth off, Bluetooth on and not connected, Bluetooth on and connected, no joy. It keeps reverting. Same goes for all the other Bluetooth settings (i.e bitrate).
So gentleman I ask you humbly, wtf? Why does the settings not stick and is this normal behavior? Is there a way I can force it to use AAC or aptX once more? I really have come to enjoy this phone but playing music in my car is a very very big factor and since AUX and USB (can't seem to play Apple Music/Google Music via USB) isn't an option, I'm stuck with Bluetooth.
Thanks in advance,
Have you made sure dual audio is disabled???
If not, go to Bluetooth, turn it on, hit the tripple dots in the top right and tap on "Dual Audio"
Make sure it's off and now try changing to AptX or whatever codec works best for you.
Disable / re-enable Buetooth and see if it sticks. (Try rebooting too)
Also, Bluetooth codecs will automatically change if the device you're connecting to doesn't support your choice of codec.
Keep me posted

Hi Corey,
Thanks for the response. Unfortunately, the above didn't work Dual audio was disabled, I enabled it and disabled it again. I tried changing the codec and bit rate but the result is the same, the moment I close the menu or turn on Bluetooth, it reverts back to SBC and Best Effort bitrate. I should mention that when I turn on the Bluetooth, it doesn't connect to anything, the only paired device at this point is my car.
Interestingly enough, if I don't close the menu but just hit the middle button, the settings will stay as is and the audio is great. What I haven't tried yet is closing the menu after a 'good' connection is made to the car. It may be that the setting sticks but the menu says otherwise. But I can definitely confirm that if I close the menu and then connect, the audio is garbage.
As for the compatibility of the car's Bluetooth, well it's a Ford SYNC2 system which from what I can see is actually quite basic. I am starting to this the problem isn't as much the codec, but rather the bitrate at which the phone is playing/sending music across the Bluetooth.

I'm not gonna' lie, I'm not very impressed by the Bluetooth on the S8... or Bluetooth in general.
It's lousy most of the time, mine always distorts and especially around emergency vehicles... (Could be interference from their coms???)
If possible, just stick to good 'ol copper wire
I can't imagine wireless audio not ever being interfered with and will always stay wired.
Also, try a music app called Poweramp.
It has many settings involving latency etc. It has a trial for 2 weeks and is worth EVERY penny if you decide to buy IMHO.
Try the build version first, if that doesn't have settings that you need, try the alpha version.
It has lots of latency settings etc
I'm guessing higher latency = better results as it has more time to be pushed over BT before the sound is reproduced.
I'm probably wrong though.
Can't beat lots of settings tho aye.

Morning Corey,
Yeah so my situation at the moment is to have my old iPhone in the car at all times as a glorified bluetooth player. I've also gone out and bought an auxiliary cable for when the iPhone's battery dies on me (happens more often than one would think). And to have a charger for the iPhone, charger for the Samsung and aux cable for the Samsung all plugged in becomes really messy.
It must be something to do with the Bluetooth 5 feature. I don't know what version the iPhone is (cba to check) but it works like a dream.
Wish we had some form of backwards compatibility or a feature to force an older version with Samsung. Just sucks buying a phone which is really not cheap in ZA just to have the music sound like a 300kb MP3 played on Winamp with the treble bars turned up all the way.
I'll try out the app you suggested mate, thanks!
