Your TRRS comment in particular got my creative juices flowing. I have a ham radio handheld microphone with a TRRS plug on it, and while it's wired COMPLETELY wrong for a TRRS headset, plugging it in and yelling into the speaker while recording with Audacity shows audio levels on the VU meter, and I can play it back properly. This tells me the Gen8 Thinkpads have a TRRS jack and that the azalia(5) driver microphone input is using the back-most contact as microphone input regardless if a device is plugged in (hence the very low level of static-looking movement on the VU meters in Audacity when trying to record earlier). I am positive I can just go get a cheap TRRS headset and I should be good to go. I do also have a broken-in-two Turtle Beach gaming headset my wife used to use, with a USB sound device built-in. Plugging that in and frobbing sndiod's flags per the Multimedia FAQ, I was also able to record audio from snd/1 handily, so I now have two quite reasonable options for all my streaming/recording/conferencing needs. I'd love to help test patches for the integrated mic should someone attempt to tackle it. I'm not much of a software developer, though, and don't have much to add aside from testing. Ty, --ax0n
