Comment 20 for bug 83015

Argh - I have the same problem today on Feisty release version. After a reboot I was surprised to find that the HDA Intel sound card was not listed in my playback devices. It was previously recognized - as far as I can tell, no configuration had changed between reboots.

My dmesg shows the same issue (cannot find slot, error creating card, probe failed with error -12).

I also have two saa7134 cards, and they are also mapped to indices -1 and -2 in the alsa-base config file, where the snd-hda-intel driver is explicitly mapped to index 0. This is to keep the SAA7134 cards from becoming index 0 (which otherwise happens randomly, and then ALSA audio playback is screwed up because card 0 is default, but the SAA7134 are capture cards with no output devices). I'm on an Asus P5B Deluxe motherboard.

I can blacklist saa7134 in /etc/modprobe.d/blacklist, but then the SAA7134 cards are inactive which is not very useful in MythTV box. It seems at this point I either have TV capture or I have sound output.

Any ideas would be most appreciated before my wife starts getting upset about the broken MythTV and pining after TiVo!
