"SampleRate"=dword:0000BB80

I'm intrigued. What exactly does this improve?

This makes the sound quality much better -try it - it just sounds richer/not as tinny with this hack..

Does it work on just BT Stereo headphones or does it also help with a headset?

Am i suppose to add the the sample rate or should it show up after making the changes...snd does it affect battery life? im using a samsung wep 250, 100 or something.

when i manually entered the above values using total commander there was no difference in stereo bluetooth sound but after importing the actual reg file the sound is much fuller, less tinny and static is drastically reduced.

thanks!

I've copied the .zip folder you posted and I've placed it on the storage card for my ppc. From there where am I supposed to place this file??

One problem I have noticed on my Sprint Touch when using the above A2DP settings is that I lost the ability for simultaneous bluetooth connections. With the above settings, I can be listening to BT stereo flawlessly but when I connect my outboard BT GPS receiver to the Touch, I lose the BT stereo sound completely. When I turn off the GPS receiver, the BT stereo comes back on. I believe the above settings maybe too bandwidth-intensive to allow for simultaneous bluetooth connections or it could be the limitation of my BT stereo headphones (Jabra BT320s). Others have recommended setting Bitpool and MaxSupportedBitPool both to 48 but the problem of GPS and AD2P working together still remained with my hardware. I finally compromised and set Bitpool and MaxSupportedBitPool of 40 and now I can use my GPS and Bluetooth AD2P concurrently.

For those who have done this tweak and have a GPS receiver, you may want to test to see if you still have simultaneous BT connections working. If you don't have GPS, try listening to your BT Stereo headphones and transfer files at the same time using Bluetooth Explorer.

Hope this helps.

Check this thread for A2DP settings and a little program I wrote to do all the reg changes, so you can experiment without having to manually change the settings everytime.
1 note, that is in that thread too. the usejointstereo should be 0 or 1. There is no documentation that says 2 is valid. the system probably sees 2 and uses 0(null)

Hi, Do you know of a hack or tweak that would make the sound on a call less tinny too? That's where I have the tinny sound.

I just made a compilation of the hacks in here. It's a word doc. No sense in searching the whole thread for one hack.
