Title: [20ALCTO1WW, Realtek ALC292, Black Mic, Left][Lenovo ThinkPad X240] external mic has no sound at all Status in HWE Next Project: Confirmed Status in alsa-driver package in Ubuntu: Confirmed Bug description: During this test, an error dialog was thrown, reading: The following mixer control(s) might be incorrectly set: Mic is at 0.0% Mic is muted Please try to fix that (e g by running "alsamixer -D hw:PCH" in a terminal) and see if that solves the problem. Would you like to continue troubleshooting anyway? However, the System Settings... -> Sound UI shows the mic as not muted. When I tried running the alsamixer command, I saw mic and mic- boost were both showing 0; I cranked them up to 100, but it made no difference. I also tried re-running this command with the mic/mic- boost still set to 100 and it threw the same error.
