No sound is heard on playback with an HDA Intel internal mic

[Sara]

Binary package hint: gnome-media

I tried changing my sound system from ALSA to OSS and my internal mic *worked*...but I had such severe problems using OSS in general that I had to do a clean install of Ubuntu. I also tried openSUSE and Debian and nothing had changed for the better (now I'm back to Ubuntu). I would really like to use my microphone without having to try OSS again (and, furthermore, understand how the mic worked in OSS but not ALSA; could it have to do with how I had to change my default card in OSS for the sound to work? More specifically, the mic recorded on the default, but playback--along with all other sounds--only worked when I used /dev/oss/oss_hdaudio0/pcm3. This is what ultimately led to problems...).

In Gnome Sound Recorder the dial moves as I am (attempting) to record, but no sound is heard on playback. I don't receive any errors while recording. In alsamixer, I had to manually enable capture, and Digital is the device by default (it was Capture in openSUSE, if that helps). I don't have a Mic Boost option, only a "Mic as Output" from Volume Control. When I raise the volume on Mux, Mux becomes the device by default. Changing the device to any of the others (including and most importantly Capture) doesn't help. The only recording that ever happened with ALSA was when my mic would record whatever was playing on my computer (with a LOT of sound distortion. By the way, playback of my recordings was crystal-clear with OSS (and Windows Vista, before I became a Linux user, so it certainly can't be a computer problem. The microphone also didn't work on the Ubuntu 8.04 Live CD...

If any more information is needed, I'll try my best to answer it. I'm running Ubuntu Hardy Heron, 64-bit. My sound card is an HDA Intel, with the SigmaTel STAC9221 A1 sound chip.
