[solved] No audio except with tvtime/streamer

I am trying to capture video/audio (with mencoder, which does video correctly) on a TV card (ATI TV Wonder Pro), and I have the line-out on the TV card connected to line-in on the sound card. And when I run tvtime or streamer, while they're running I hear sound. I continue to hear sound after I quit tvtime with CTRL-C (but not with the X button). streamer, as I said, lets me hear sound, but the files it generates do not contain any. There's probably a way to fix that, but I'm more interested in getting mencoder to work with sound. I don't see any changes on kmix/aumix/alsamixer when tvtime is started/stopped.

Also, even when I have started tvtime and CTRL-Ced it, so I hear audio, mencoder still doesn't record audio. I'm using this command:
mencoder  -lameopts cbr:br=256:mode=0 -tv alsa:driver=v4l2:outfmt=rgb24:freq=271.25:brightness=45:contrast=30:hue=40:saturation=40:alsa:amode=1:adevice=hw.0,1 -ovc lavc -lavcopts vcodec=ljpeg -oac mp3lame tv:// -o test.avi
I took amode=1:adevice=hw.0,1 and the lameopts from another topic here, but none of those options seem to do anything.

How can I record TV audio with mencoder?

Self-solved. The magic word:
v4lctl volume mute off
(Sorry if there's a better way to say I solved it.)
