Upon further twiddling with pavucontrol, I was able to get it to work /sometimes/. I'm noticing that, upon bootup, pavucontrol lists the monitor and the input of the card among the inputs, but there is no level indicator next to the input itself. The monitor has a level indicator, but it always shows 0. I've twiddled around with killing pulseaudio, plugging in a webcam to get a second mic, turning the internal card off/on, setting it to analog output only, and so forth ... sometimes a level indicator appears underneath the input of the internal card and updates slowly. That is, the webcam's microphone's level indicator updates all the time and twitches around 75%, whereas the internal card's input's level indicator updates only about once per second. Nevertheless, when the level indicator appears, recording from the internal mic works perfectly (as tested with skype call testing service). I have no idea why one would have an input without a level indicator. I'll try to keep poking around to try and come up with a reliable way of bringing about an internal input from which I can record. Please help me if you know a sure-fire way to make this work! TIA, Gabriel
