Public bug reported: I have a Gigabyte GA-H61M-S2PV motherboard that has on-board audio, listed by the motherboard manufacturer as "Realtek ALC887 audio codec". Lspci reports it as "00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 05)".
Before I continue, I should note that I am aware of a workaround for hte problem: adding "snd-hda-intel model=generic" to /etc/modprobe.d/alsa- base.conf. This makes the card marginally usable, but there is no microphone or additional channels, so this is not a *solution* to a problem, merely a workaround. The ALSA modules are auto-loaded (modules snd_hda_codec_realtek, snd_hda_intel, snd_hda_codec) but alsactl and alsamixer don't work: $alsactl init Found hardware: "HDA-Intel" "Realtek ALC887-VD" "HDA:10ec0887,1458a002,00100302" "0x1458" "0xa002" Hardware is initialized using a generic method /usr/share/alsa/init/default:26: control element not found /usr/share/alsa/init/default:26: control element not found /usr/share/alsa/init/default:48: control element not found $ alsamixer cannot load mixer controls: Invalid argument The following output is visible in "dmesg": [ 51.323553] hda_codec: num_steps = 0 for NID=0xc (ctl = Front Playback Volume) [ 51.509438] hda_codec: num_steps = 0 for NID=0xc (ctl = Front Playback Volume) [ 51.516123] hda_codec: num_steps = 0 for NID=0xc (ctl = Front Playback Volume) ...
