[Bug 416190] Re: Pulseaudio produces overdriven audio on Plantronics DA40 adapter

[Raymond]

can you post the output of amixer and lsusb -vvvv of da40 and da45 ?

do these device also have a mono playback volume control?

you have to follow up your case in pulseaudio-discuss mailing list about the  clipping of the mono playback,
the clipping may also ocurr with recording mono with a stereo mic or 4-channels mic
