Description Christian Hoffmann (RETIRED) gentoo-dev 2006-01-28 15:02:55 UTC 
After upgrading the kernel from 2.6.14-r4 (gentoo-sources) to 2.6.15-r1 (gentoo-sources) my TV audio is no longer working.
I tried it with both the internal ALSA driver (it worked before with that) and the alsa-driver package (didn't try that before).
Sound: Multimedia audio controller: Cirrus Logic CS 4614/22/24 [CrystalClear SoundFusion Audio Accelerator] (rev 01)
TV:
Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11)
Multimedia controller: Brooktree Corporation Bt878 Audio Capture (rev 11)

The audio signal goes out of the TV card and into the soundcard line-in. I checked the volume of the line-in audio canal in alsamixer and it seems to be Ok.
When I start tvtime I only hear a short noise. When changing the channel in tvtime it's the same. The TV picture works as before, as well as the tuner, only the sound makes problems.

dmesg | grep bttv:

Comment 1 Daniel Drake (RETIRED) gentoo-dev 2006-02-10 08:58:34 UTC 
Is this reproducible on the latest development kernel (currently 2.6.16_rc2)?

> Is this reproducible on the latest development kernel (currently 2.6.16_rc2)?
Yes, it doesn't work either.
Comment 3 Daniel Drake (RETIRED) gentoo-dev 2006-02-11 02:28:13 UTC 
Please file a bug report against 2.6.16-rc2 for this upstream at http://bugzilla.kernel.org and post the new bug URL here.
Comment 4 Christian Hoffmann (RETIRED) gentoo-dev 2006-03-30 08:39:11 UTC 
Sorry, I forgot to report this bug (I've used kernel 2.6.14 for some time now..).
Now I found a workaround: I have to unload the bttv module (rmmod bttv), then load the snd_bt87x (modprobe snd_bt87x) and then load bttv again. After these steps the sound is working again (although it is louder than before).

Should I file an upstream bug now? I'm not really sure what triggers this bug. The kernel? Something different (udev?)?
