I can't seem to unmute my tv tuner card. I've read several other posts in which a particular firmware file (v4l-cx25840.fw) was missing or failing to load. But, I can see in my message log that the firmware does load successfully. I've tried unmuting with several combinations of options set.
Right now, the only module option I have set in modules.conf is "options ivtv tuner=2".
