Hi,
The sound comes from alsa device. Several em28xx types provide
standard USB audio. So,
snd-usb-audio handles it. That's why you need
alsa:adevice=hw.2,0:forceaudio at mplayer.
... but thats my problem.
sound doesn't appear inside mplayer, even with the command line options
set to use the "external" alsa device. However, "arecord -D hw:2,0 -r
32000 -c 2 -f S16_LE | aplay -" plays the sound, but only before mplayer
tried to access the sound card
When trying to play sound with arecord again after mplayer tried to
access it, I have to re-plug the card to get it playing sound over
arecord again, video only seems to not break it. There is no error
message or something in arecord when it's not playing anything, just
silence and the same command line output.
Is there maybe anything with the sample format S16_LE or something that
confuses mplayer/the driver/whatever?
Strange problem...
mplayer output (mplayer -v -tv
driver=v4l2:input=0:device=/dev/video1:alsa:adevice=hw.2,0:forceaudio
tv://):
