Hi Stan, Thanks for your helpful comments.

I can't tell exactly when it stopped working since I didn't need the mic for about a week. I had been successfully using the mic before. > I don't think this is an alsa issue.

Just for the sake of completeness I'm posting screenshots from both alsamixer and pavucontrol.

I see no suspicious messages. But I do see the following: pulseaudio[1455]: module-alsa-card.c: Failed to find a working profile. pulseaudio[1455]: module.c: Failed to load module "module-alsa-card" (argument: "device_id="29" name="platform-thinkpad_acpi" card_name="alsa_card.platform-thinkpad_acpi" tsched=yes ignore_dB=no card_properties="module-udev-detect.discovered=1""): initialization failed. Although I don't understand the error, I don't think this is related to my problem as I see this is also present in old log files (from the time when the mic worked). > Try using arecord to record directly from alsa into a wav. > arecord -d 10 -f cd -t wav foobar.wav > If the default device doesn't work, you can try > arecord -d 10 -f cd -t wav -D plughw:0 foobar.wav > or > arecord -d 10 -f cd -t wav -D plughw:1 foobar.wav > > If none of these work, I would suspect hardware failure. None of these worked and I also looked at the alsa-devel thread you referenced; I don't think that my issue is similar. I guess that means this is hardware failure. Hopefully I won't have problems with warranty since I bought this in Canada, and now I am in Switzerland. :-| -- Suvayu Open source is the future.
