[Bluez-devel] Problem with A2DP & HHB-750

[konrad003 <konrad003@tlen.pl>]

Hi. I've got Siemens HHB-750 bluetooth headphones and Dell Latitude X1 laptop with dell BT card:
Bus 002 Device 003: ID 413c:8103 Dell Computer Corp. Wireless 350 Bluetooth

Pairing is ok, connecting too, but it still skips (like buffering?). It depends on 'sbcbitpool' in config. For example for sbcbitpool=4 it skips every ~9 seconds. For sbcbitpool=32 it's about 300-500ms :(
I'm using Feodra 7 with kernel 2.6.22 (2.6.22.1-41.fc7).

There is a dump from a2dpd:
