My internal mic isn’t working or picking up when using Google Voice. I was able to record a wav using arecord after opening alsamixer and turning on digital in the capture section but still not luck using internal audio with applications.
Are you using pulse ? Did you try enabling it and see if that works ? This link holds some useful information on how to do this : SDB:Pulseaudio - openSUSE
I disabled Pulseaudio because it was causing me problems. I would like to avoid it if possible but if it’s the only way to get Google Voice working then I’m screwed.
I don’t think it is the only way but might be worth a try. If that works maybe you will be able to sort out your other problems with pulse. I have this problem with skype. Without pulse the mic is very quiet even though setting all the volumes to maximum. With pulse it works out of the box.
