[MPlayer-users] Can't get mplayer -tv to play back audio input

I'm trying to play (and later on record, using mencoder (?)) video from a
USB frame grabber device. The following shows video, but not audio. Why?
mplayer -tv 'device=/dev/video0:driver=v4l2:alsa:adevice=hw.0,0' -vf
I've connected my audio to the builtin audio, hw:0,0, and can confirm that
arecord -r 48000 -D hw:0,0 -f S16_LE -c 2|aplay
plays back the audio. So, what's missing for mplayer?
IIRC mplayer shows a line that says "no audio".
(Since hw:0,0 is standard builtin audio of the PC, I don't expect it to
need special sample rate parameters or such to work.)
This is on Ubuntu 13.10.
