Oh, sorry, I didn't mention type of microphone :(. It goes about
internal one I guess (or in terms of snd_hda 'Connection type=Fixed').
External ('Connection type=Jack') works fine.

Attepts to record using rawrec\rawplay, skype test call, audacity   etc.
produce only monotonous hissing.

Not sure if I understood you correctly regarding mixer settings. Well,
all channels are set to 100, i.e. smth. like:
mixer | egrep -i 'mixer' | awk ' { print $2; } ' | xargs -I % mixer % 100

Unfortunately, I have no 7.2 alongside. Will try to obtain verbose
output from it and compare against current.
