ffmpeg w/bktr no sound

I'm still working on getting ffmpeg encoding to work and the video
is fine but I get no audio. I have mucked with the mixer settings and
such to no avail.

I use fxtv to set the channel, for now and when I turn off
line in the mixer the fxtv audio dies. It is plugged into
the sound cards line in. Based on this I set mixer recsrc 
to line, but still nothing. It's broadcast NTSC signal.

Any other ideas ?

capture command
ffmpeg -vcodec mpeg1video -b 1200 -s 320x240 -y -t 10.0 test1.mpg
ffmpeg -vcodec mpeg4 -b 1200 -s 320x240 -y -t 10.0 test1.avi

I play the results with mplayer.

here's the dmesg and mixer settings if that helps.
