Comment 16 for bug 776065

I tried in 12.10, booted from iso file quantal-desktop-i386.iso. I couldn't get the GUI working so I booted into text mode and used fmtools. I hear my favourite radio station.

$ fm 99.05
Radio tuned to 99.05 MHz (radio does not support volume control)

$ fm on
Radio on (radio does not support volume control)

$ v4l2-ctl -d /dev/radio0 -all -L
