You right, i played with different profiles. HSP controls volume on pulse, but minimal volume is still too loud. A2DP use internal volume control and i can set it as silent as i need. I made some more tests with different kernels. It looks more like kernel issue. I get different oopses and it looks like 3.5.0 sounds better then current master git. -- Regards, Oleksij
