Hello there,

My laptop's internal microphone stopped working, kinda out of the blue. Between now and the last time I used it successfully I have updated some packages and reworked some useflags, so that could be the reason. Unfortunately, I cannot tell which packages I updated. I haven't changed the kernel. So suggestions are appreciated.

- Yes, I have selected a capture channel in alsamixer
- Yes, I tried unmutting and increasing the volume of "Mic" in "Playback"
- Yes, I played with volume controls in alsamixer
- Yes, I've tried recording (I normally use audacity to record) but nothing is recorded

Thanks in advance!

Audacity and skype essentially, but I could try Ardour3 (thus, using jackd instead of alsa).

EDIT#1: Just tested. Ardour3, as Audacity, records a straight line of silence.
