Finally after couple of the ROM re flashes I found what file can be transfered from the TeamEOS builds to get the BT audio streaming working.
The workaround to fix the issue:
1. Download and unzip the file: http://www32.zippyshare.com/v/8042271/file.html
2. Copy the file "audio_policy.conf" to device root/system/etc
3. Reboot the Prime
Let me know if this fix works also for you.
The files are taken from the Team EOS "EOS-tf201-20120814-38" build file. Thank you guys.
