I have modified and reassembled the intel_hda driver. I tried out multiple codec_mask values (from 0 to 4).
codec_mask = 0 gives nothing
codec_mask = 1 gives ALC268
codec_mask = 2 gives a Motorola device, which is a modem on my laptop
codec_mask = 3 gives ALC268
codec_mask = 4 gives nothing
After all this I have no sound.
