Public bug reported:
After upgrading to Karmic Koala I am not able to tune my bttv v4l radio
anymore. I have been using gnomeradio for this.
In addition there were following options required for the bttv driver:
$ cat /etc/modprobe.d/local-bttv.conf
options bttv card=70 radio=1
These options used to work for last 3-4 years or so...
At this moment I get the radio/video stuff created in /dev directory,
but the radio application fail to show signal power and there is only a
white noise coming from the speakers as if the radio was not tuned
properly. Changing frequency does not seem to have any effect. So looks
like only enabling/disabling radio works.
I am not using the video card to watch anything. But at first glance it
with xawtv it looks like working.
