This is only for analog loopbacks and has nothing to do with the mic recording level. % amixer -c0 set Mic 0 Then check whether the problem persits. If yes, give alsa-info.sh outputs at both state with and without headphone plugged. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

So, it's no wonder that a mic gets some signal and sent to analog loopback when using a headphone jack. Though, in the codec design level, this shouldn't happen; the mixer widget has a mute for each input source and it's still muted in your case. Maybe Sony implemented some vendor-specific way to control the headset mic, noise-canceling or such a thing. We cannot know it, unfortunately. It's a pretty vendor-specific internal, after all. That said, if setting "Mic" volume to 0 fixes the issue, it's the valid solution :) -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
