To tell you the current active input, freq, mute status, etc., use: # v4l2-ctl --log-status As another data point, since it looks like your card supports FM radio, you can test that (with a station at 107.3 MHz for example): # ivtv-radio -f 107.3 Also to turn on verbose debugging of your choice: # /sbin/modinfo ivtv # modprobe -r ivtv # modprobe ivtv debug=... > I also had some trouble with ivtv last year (video related, not sound > related) and solved my > problems by compiling ivtv from source.

The latest V4L/DVB staging repository has an ivtv version of 1.3.0 in it, if you feel like compiling from source: http://linuxtv.org/hg/v4l-dvb/archive/tip.tar.bz2 tar -xjf ..., make, make install, make unload, modprobe ivtv But beware of v4l-dvb compilation and module problems with Ubuntu Hardy Heron: https://bugs.launchpad.net/ubuntu/+source/linux-ubuntu-modules-2.6.24/+bug/220857 Read all the comments and then decide if you really want to go through compiling from source on Hardy Heron. It looks like it won't be straightforward.
