I get no sound afterwards when playing with mpalyer with all these:
Code:
/usr/bin/mencoder tv:// -tv driver=v4l2:input=0:norm=pal:chanlist=switzerland:width=320:height=240:outfmt=yuy2:device=/dev/video0:alsa:adevice=hw.0:amode=1:audiorate=32000:forceaudio:forcechan=1:buffersize=64 -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=1200:keyint=30 -oac mp3lame -lameopts br=128:cbr:mode=3 -ffourcc divx -endpos 1819mb -o "tvchannel.avi"

I tried this too :
no sound still
ffmpeg
ffmpeg -threads 2 -vd /dev/video$DEV -r 29.97 -b 800 -s 640x480 -vcodec h264 -qmax 51 \

-ad /dev/dsp$DEV -t $TIM -f avi -y $DIR/$FIL.avi
* a/v sync drifts a bit -- not reliable
* encoding efficiency is high, but frames are dropped silently
mencoder

* creates files that don't stream correctly in VLC -- we've not got to the bottom of this
* encoding efficiency is somewhat below ffmpeg and transcode -- cannot capture to full 640x480 size without dropping frames
* superior to the others in its ability to accept a much fuller set of x264 encoding parameters

my dsp1 is the sound card that makes sound when playing tvtime
I tried to play too with alsa
mplayer gives:
