Increasing Bluetooth(a2dp) sound quality - Samsung Epic 4G Touch

So... I just recently installed a bt a2dp compatible stereo receiver in my car and when bluetooth audio is connected it sounds mediocre/ok.. BUT I remember several years ago on windows mobile phones being able to increase bitpool or something in the registry that largely improved a2dp sound quality .. I've been out of the loop on A2dp as of late .. is there any similar hacks or roms that provide higher quality a2dp? Anyone... anyone....

What type of headunit. I know that sony has the option when you adjust bass/treble, etc that a bluetooth option is available to boost the input via BT. I used that in my wife's vehicle.

It's a Kenwood Excelon receiver / KDC-x996 .. and I am able to adjust treble/bass on the headunit when connected via a2dp .. and it does sound ok.. but I remember when adjusting the bitstream/bitpool the audio quality would go from ok and flat to near cd quality .. it really was very noticeable.

listening to MP3 windows media on bluetooth headset?

hi everyone. is it possible to listen to my windows media palyer mp3 and other audio in a bluetooth headset? i bought a BT headset and got it to wotrk on my xda2 for incoming and outgoing calls...but when i listen to my audio in windows mobile, the sound still comes out of the xda2...
i hope you guys have something for this...
thanks.
I have a PPC-6601 with the same issue. The platform apparently does not support "audio on demand" over bluetooth. There may be 3rd party software or a bluetooth stack tweak that fixes this but as of yet I have not found one. If it exists it is probably on this site, but I'm still searching.
Hopefully someone will post a fix.
This also causes voicecommand to not work over the bluetooth, which means that a wired headset is far superior to a bluetooth one on these phones. Hopefully it is not a hardware limitation.
good luck to us.

Its not a limitation... but the device should support AD2P profile... which is not still in there.. will will have to wait for it
Hey guys,
check out PDA2K_BroadcomCorp_BTUpdate.cab on this forum:
http://forum.xda-developers.com/viewtopic.php?t=14329
I believe this adds the AD2P and keyboard profiles to the phone. When I installed it on mine I saw a new profile for bluetooth high quality audio headphones. Unfortunately my bluetooth headset (Logitech mobile freedom) doesn't seem to support AD2P. I was hoping to get low quality audio on demand through the headset, not necessarily high quality audio. My goal is to get microsoft voice command to work over the bluetooth headset speaker and mic.
Let me know if you have any ideas for getting audio on demand over my bluetooth headset, and if you have a good set of bluetooth headphones that support AD2P, the file at the link above should get it working if you have the broadcomm/widcomm bluetooth stack.
Thanks for the link
Thanks for the link, will have to search for the update for PDA2k....
pda2k update
that file should work on any pda using the broadcomm bluetooth stack. it adds the high quality audio profile and keyboard profile.
i am looking for a way to get a headset profile to behave exactly like a wired headset. apparently this is not an option.

Stereo Bluetooth Headset

Is anyone using either Sony Ericsson HBH-DS970 or Nokia Wireless Stereo Headset HS-12W with Artemis? If so, how's the audio quality? Do you need to install extra software? Do all the buttons work? And do track titles show on the display?
Thanks!
Rick

Problems Solved
I just recently got my P3300 and a nice Sony Ericsson HBH-DS970. I had a lot of problems with the original Windows Mobile 5 at first. It recognized the unit as a2dp and I set the P3300 tu use a2dp functionality of the sony headphones. NADA! Nothing happened. I could just use it as regular hands-free. Then I found this site and first upgraded mu ROM to
PDAMobiz_Dopod_P800W_AKU301_v1.1.2_PowerMap.rar
I didn't like it because it was for Asian market, no localization etc. and some problems...
Then upgraded to
Tom_ART_v2.00.02_CB.rar
Brilliant!!!! Looks like WM6 and has a lot of new functionality +
working A2DP profile. Now the Sony Ericsson HBH-DS970 is working 100%. No bugs, no music while ringing or other problems. Just perfect!
The only disapointment - There is no Radio! In order to run the radio you must use the original hands-free. they say it is because it uses the wire as antena. I tried to hook both the Sony Ericsson HBH-DS970 and the original hands-free -> the sound coming only from the original. SORRY.
I read somewhere that the Nokia model has a built in Radio. So if you need the Radio go for the Nokia one. Though they say the sound from the Sony Ericsson HBH-DS970 is way better! If you prefer MP3's with better sound go for the Sony.
Hope this helps.
i use the nokia hs 12w and the sound quality is excellent.
Do you guys have enabled or disabled the registrykey "UseJointStereo"?
I'm using the HTC BHS100 Bluetooth together with a V-Moda Vibe. When I enable this key (value set to 1) I have superior sound quality but in jointstereo. When I disable this key (value set to 0) to achieve real stereo sound I hear a high pitch noise and the sound is far from superior but in real stereo. This really anoise (typo?) me alot and it doesn't matter whether I'm using the original earphones that comes with the bluetooth or the v-moda earphones or even my full sized dj headphones.
All in all i'm just looking for a wired solution to get the superior stereo sound but that is a problem too. Because a mini-usb to 3.5mm adapter doesn't disable the built-in speaker when listening to music (using an HTC Y cable)

Have you tried this update: http://www.europe.htc.com/support/software/htcp3300.html
HTC:
"HTC audio Drivers
Downloading and installing this driver update will provide your HTC mobile device with the latest available optimised software for use with the following accessories:
YC A120 Y-Cable adaptor
RC W100 Remote Controller
RC E100 Remote Controller"
Tried it just now but I get the message that I already have the latest drivers installed and then it ends the installation.
I'll try to put back the original rom and then install the driver to see if it makes any difference. That is if I'm able to put it back somehow (extended rom has original rom but hardreset still installs the modified rom).
Finally...after installing WM6, the device recognise the Y cable as a headset (registry automatically change value into 1) and now I can enjoy music in full stereo quality. WHOOHOO
Hi,
Is there any way to set the bluetooth stereo headset connection to default stereo? sorry about my english.
so If i connect may stereo headset to the phone the defaul is mono headset i have to go to bt settings and change the profile to stereo after that working fine, I can handle incoming calls etc. but I have to change the profile after reconection again. If I uncheck the headset and handsfree profiles then the stereo working fine but i cant handle the incoming calls from the haedset only with the phone.
so is there a solution to keep the default profile stereo and keep the other two profil in live?
it tries to you works in stereo
Quick question for anyone with a BT stereo headset - if i get a BT dongle, could i connect the headset to a PC and get voice comms via teamspeak to work? Assuming that the dongle and headset does all the A2DP and other profiles?
Basically I'm just trying to see if its feasible - It'd be nice to use the headset for music with the phone, then use it as a wireless headset for games and voice comms when at home.

Yes, and with VOIP & MSN etc. too. The headset appears in the audio properties box on windows or the app you are running.
Thanks -
Before i go and splash out on one - can you confirm a headset that will deliver quality stereo while using the mic
Virtually everywhere i've been, they say that as soon as you use the mic, it will drop down to 8khz mono for sound as it switches from A2DP to the headset one.
If you or anyone have a BT stereo headset, is there any chance you can play a normal 3D game and see if you can talk over teamspeak without it dropping to mono?

I think u need to get headset with multipoint headset if u want keep in live the phone and the PC connection same time. like jabra BT8010 or BT320s.
I use Jabra 5020 (mono) and working fine for Voip and Phone same time.

Bluetooth Audio One Sided

When I connect to media audio via bluetooth in my car, I can only get audio out of the left side speakers. This is repeatable on different apps that play music. When I play a radio station in my car I get sound out of both sides.
What can I check to help diagnose this problem and hopefully fix it?
Thanks.
Does anybody else have this problem?
Does your car audio system support A2DP stereo Bluetooth profile ? Probably it does, otherwise I don’t think you can stream audio with just the Hands-free (HFP) profile (which is a low quality link meant only for calls). Mine works fine in stereo with my car’s audio system. Try deleting all the BT settings from your car and initialize everything from the beginning.
Iam verry sure that your audio car not support A2DP because in my car i can use for stereo...try to see the specification for your car audio bluetooth..
Sent from my HTC One X using xda app-developers app
It works fine when I use my Galaxy Nexus. This makes me believe it supports A2DP. This problem is unique to the One X for me. Did I get a bad phone?
Also, when I crank the balance over to the side that doesn't work I can hear it a little bit, but it's crackly and distorted.
EDIT: Problem solved. Re-seated the wiring in the sound system and everything is fine now.

[Q] Bluetooth Audio Quality

I've searched but the issue has not been brought up yet afaik.
So i bought a bluetooth usb headset, which also has an audio-cable connection if needed when battery is low. this allowed some poor experience:
the audio sent via bluetooth is terrible compared to using the cable. i've read that its down to mp3 being compressed again and then sent via the BT signal.
I've seen solutions for other phones using software or messing around with some parameters (e.g. bitpool from 32 to 53 or whatever). what can i do to improve audio quality as this definetly just makes listening to musik via BT impossible?
the headset is a philips sbh9100
cheerio
does no one have an idea?

Problem With A50's Bluetooth audio playback in cars and other devices

While playing audio on Car Stereo via A50's Bluetooth, The Audio got crackles and skips, even in receiving phone calls,
I have tried changes in developer options in Bluetooth menu, and also disabled battery optimization for Bluetooth but nothing changed :crying: Similar situation while playing in JBL Bluetooth speakers
At other side my old sony Xperia C3 D2502 is working awesome on same car Stereo.
Same problems
If you use powersaving mode disable it
Maybe the problem is from this option
You didn't mentioned which rom and baseband. I use BT with Anker BT headphones, Roidmi2S and used it with Roidmi1 and a Yatour Car unit without any crackles and pops. I'm on May update, XXUASE3, OXM CSC.
