Comment 15 for bug 29789

My bt878 card did work without problems in Ubuntu 5.10 when recording from the TV-card's line-out, so it'd seem like a regression. It's a weird combination of loading order and "modules handling the same thing" stuff. blacklisting bt878 allows snd_bt87x to function properly (without blacklisting snd_bt87x is loaded but nothing seems to be initialized).

A complexicating thing is also the amount of methods that may be used for recording. Recording from line-out shouldn't require snd_bt87x at all, snd_bt87x is for directly recording from the tv card either the analog way or digital way (both provided by snd_bt87x, and supported only by some cards). In 5.10, I didn't even try the direct recording, but now some of this new ALSA/DVB (?) stuff is breaking even the sound output from line-out to line-in depending on the modules loaded. And if that's not enough, I have recording problems even using Gnome's sound recorder with my HDAudio sound, but at least the sound should be heard when the TV card is connected to line in.

Also, there isn't even a good documentation available about what _is_ the relationship between bttv, bt878, btaudio (gone?), snd-bt87x... modules. I don't even have a digital TV card but still apparently some DVB stuff is also included in some of those modules? And some forum messages are indicating that that "dvb stuff" is also trying to "handle" the audio part.

I hope there is at least someone that actually understands the whole picture.
