I have an Ice Lake laptop with 3 8-channel HDMI outputs. My kernel appears to have the appropriate modules loaded for the card, including snd_hda_codec_hdmi. Here is the information for one of the channels from /proc/asound/card0/codec#2.
[…]
But as far as I can tell ALSA is turning them into 2-channel outputs. At least I can not see any surround channels in alsamixer and I can only play 2-channel sound to them using speaker-test. How can I find out where the change from 8 channels to 2 channels is happening? And how can I get 7.1-channel (or 5.1-channel) sound to these outputs?
