Trying to get hdmi audio out on an Acer Aspire X1200. With 1.0.18a, I only have one codec available for hda-intel nvidia 8200 board - the realtek one. If I compile with only the nvhdmi one: ALSA_CARDS="hda-intel" ALSA_CARD_OPTIONS="hda-codec-nvhdmi" ALSA_DEBUG="y" then I get no sound cards and see the following in dmesg upon loading the snd-hda-intel driver. I've heard reports that people have this working, but I've yet to see an aplay -[lL] and a proc/asound tree from one of these folks. [ 117.392433] HDA Intel 0000:00:07.0: PCI INT A -> Link[AAZA] -> GSI 21 (level, low) -> IRQ 21 [ 117.392486] HDA Intel 0000:00:07.0: setting latency timer to 64 [ 117.392493] ALSA /usr/src/modules/alsa-driver/pci/hda/../../alsa-kernel/pci/hda/hda_intel.c:2130: chipset global capabilities = 0x4401 [ 117.428527] ALSA /usr/src/modules/alsa-driver/pci/hda/../../alsa-kernel/pci/hda/hda_intel.c:771: codec_mask = 0x9 [ 117.784032] hda-codec: No codec parser is available [ 117.784064] ALSA /usr/src/modules/alsa-driver/pci/hda/../../alsa-kernel/pci/hda/hda_intel.c:1258: hda-intel: no codecs initialized [ 117.784173] HDA Intel 0000:00:07.0: PCI INT A disabled alsa-info.sh in this state is here: http://www.alsa-project.org/db/?f=0453d13aa81ce9b444481276b4cc1410f0fa364d ... as I was fiddling, turns out that this is likely due to the the "probe_mask" option I had in my modprobe.d/alsa-base config file, which was preventing the nvhdmi codec from loading. After I removed that, I now have hdmi audio working! To build the package in Ubuntu I had to enable the nvhdmi codec with the ALSA_CARD_OPTIONS above in /etc/alsa/alsa-source.conf. Then ensure I had no options in /etc/modprobe.d/alsa-base.
