OpenSuse 11.1 (upgraded from 11.0) with gnome e pulseaudio on a XPS laptops with SigmaTel 9228 chipset (ICH8 family).
Audio out runs perfectly but I cannot hear anything from microphone. In particular I’m trying to use Skype which OS 11.0 was working very well.
I also tried by installing gamix because alsamixer shows very few controls.
I am a KDE user. I do not use gnome, nor gamix, nor alsamixer, nor Skype. I can not provide support for those apps/desktops that I don’t use.
But you could test basic mic functionality.
When I test my mic, I typically use a simple arecord command. ie something likearecord -d 10 myrecording.wavorarecord -d 10 -f cd secondrecording.wavwhere “-d 10” sets a 10 second recording. I then play back the recording with xine or mplayer or xmms (or any audio playback program).
When advising of the results of that, please make it clear as to whether you were trying your Internal mic or your external mic.
