Recording worked fine before (the only problem was a lot of underruns) but now, I can't even seem to start recording. Simply running "recordmydesktop" gives the following output (from error log):

recordmydesktop -o /home/metaleks/out.ogg -fps 24 --full-shots -channels 1 -freq 22050 -device hw:0,0 -v_quality 63 -s_quality 10 -workdir /tmp --on-the-fly-encoding --compress-cache --follow-mouse --no-frame -width 448 -height 336


Buffer size adjusted to 4096 from 4096 frames.
ALSA lib pcm_hw.c:1207:(_snd_pcm_hw_open) Invalid value for card
Couldn't open PCM device hw:0,0
Error while opening/configuring soundcard hw:0,0
Try running with the --no-sound or specify a correct device.

Running with the --no-sound flag works, but defeats the purpose of having a microphone. I am using the newest version. Any ideas?
