bt878: radio frequency stuck

bt878: radio frequency stuck

[Emile Joubert]

Hi,

I have the same symptoms as the ones described here:
http://article.gmane.org/gmane.linux.kernel/1214773

I have the same model card (37284) which also stopped working at commit
cbde689823776d187ba1b307a171625dbc02dd4f. Since that commit the radio
produces white noise and changing the frequency has no effect on the
sound. I've tried kernel 3.8.0-rc7 and the problem still exists in that
version.

Please let me know if there is further information I can provide towards
a solution, or if there are any patches I could try.

Try this branch:

http://git.linuxtv.org/hverkuil/media_tree.git/shortlog/refs/heads/bttv

Of particular interest is the patch "bttv: set initial tv/radio frequencies".
You could actually try applying just that patch first. If that doesn't
work, then try the whole patch series.

If none of that works, then let me know and we can do some more debugging.

Regards,

I'm pretty sure this will work. I have the same model and I can confirm lots
of problems in the current driver, but after my fixes it all works again.

I can confirm that on that branch the tuner works for me too.
Thanks!
