About my problem, the audio card with the latest patches seems to work (but great noise when nothing is playing is present, i also tried to mute everything in alsamixer) so i could say "it works with model=auto" I applied the patch, and build the kernel, this is my lastest alsa-info: http://www.alsa-project.org/db/?f=61aa4129d0ea771ebc7226ea80c5c3ead24ef05c "Loaded ALSA modules" is empty, but lsmod says: dante log # lsmod|grep snd snd_hda_codec_realtek 298841 1 snd_hda_intel 20936 0 snd_hda_codec 62886 2 snd_hda_codec_realtek,snd_hda_intel snd_hwdep 5484 1 snd_hda_codec dante log # I notice this in my dmesg [ 12.805835] ALSA sound/pci/hda/patch_realtek.c:1842: realtek: No valid SSID, checking pincfg 0x4005e601 for NID 0x1d [ 12.805838] ALSA sound/pci/hda/patch_realtek.c:1858: realtek: Enabling init ASM_ID=0xe601 CODEC_ID=10ec0892 [ 12.805890] ALSA sound/pci/hda/patch_realtek.c:1569: realtek: Enable HP auto-muting on NID 0x1b Is normal "No valid SSID" ? Alsa-conf still not find my sound card. Sorry for the long story, but i would give you more informations as i can to help.
