My microphone has stopped working--no update or obvious change preceded this (though I did system upgrade when trying to fix it). "arecord --duration=2 --format=dat test-mic.wav; aplay test-mic.wav" plays nothing, even though the sound is working elsewhere, and the microphone works fine on my dual-booted Windows.
I've already added the kernel module parameter specified in the wiki:
>> cat /etc/modprobe.d/snd-hda-intel.conf
options snd-hda-intel enable_msi=1
I also tried raising mic boost in alsamixer: so that "alsamixer --view=capture" shows the following

Then I hear just white noise, no actual sounds.
Also, the amixer command to unmute the microphone gives a correct-looking output.
