Bluetooth wireless stereo not working? (Only mono)

[Guest hmptec]

Hi,

I have an I-Tech R35 stereo bluetooth adapter which seems to work ok. I have paired it with my Vario II and I get the option for 'wireless stereo' as part of the bluetooth options.

However, I only get mono sound. This is with either Windows Media Player or Pocket Player with all the appropriate plugins. I also downloaded the revised A2DP stack from this forum, but no change.

Can anyone advise what is wrong?

Thanks, in advance.

I think that's how the Hermes normally runs bluetooth stereo - by pumping the same audio feed into both ears! To fix this, use a Registry Editor to alter:

HKLM / SOFTWARE / Microsoft / Bluetooth / A2DP / Settings / UseJointStereo

from 1 to 0

This has the effect of "forcing" the phone to do proper stereo. At least it worked on mine with my iTech S35 clip!

Thank you XDA Developers for that tweak!

That did it! Many thanks.
