CSR BT v1.1 firmware upgrade - A2DP

[Gionames]

Hello,

I've been trying to stream stereo music from:

- computer A with a built in CSR BT v1.1 to
- computer B with an external CSR BT v2.0 dongle.

Both of computers have Widcomm 5 stack. As I saw "High quality bluetooth audio" in the audio settings of the computer A, I hoped I could use A2DP for the streaming, but judging from the audio quality I get, that doesn't seem the case, definitely!

So I was wondering if someone can point me to any resource or post where there's a firmware upgrade for my internal bt adapter (VID_0A12 & PID_0001) to HCI 1.2 (=BT v1.2). That would most probably solve the problem. I recall having seen something but can't locate it.

Thanks in advance,
Gio
