Oh thanks Kushal. I'd worked that out in the mean time, and tried what
looked most likely. Only then did I discover in dmesg this:
hda_codec: Unknown model for ALC882, trying auto-probe from BIOS...
So now I know the model name and can see the known options from the URL
you gave me. The obvious one there was
3stack-dig 3-jack with SPDIF I/O
simply on the basis that I have three jacks on the front of the laptop.
I have no idea what SPDIF I/O is, but I tried it anyway, and alsamixer
then failed to load, saying:
alsamixer: function snd_mixer_load failed: Invalid argument
So that was a no. I suppose I can try all the alternatives, I guess it
an't do any harm. There are only 9 more listed, though most sound
wrong.
