Additionally, the capture has some distortion. If I tap on the microphone I can hear the taps, so I know that the capture is working; however, it is not functioning in a manner that allows it to be usable. Everything else works great, including audio output (I can hear music and sound from videos just fine). Additionally, when I boot into windows vista, the microphone works perfectly, so it's not a hardware issue. I have scoured the forums trying to find a fix, including trying all the different models in alsa-base.conf listed for the STAC9228 and trying all sorts of configurations via alsamixer and pavucontrol including silencing the left/right channel while leaving the other at full volume. I have even tried alternate configurations via hdajackretask.
