thanks, seems like the discrete GPU audio enabling fails:
[ 3.410544] snd_hda_intel 0000:01:00.1: can't change power state from D3cold to D0 (config space inaccessible)
[ 3.410561] snd_hda_intel 0000:01:00.1: can't change power state from D3hot to D0 (config space inaccessible)
[...]

[ 3.509225] hdaudio hdaudioC1D7: no AFG or MFG node found
[ 3.509226] snd_hda_intel 0000:01:00.1: no codecs initialized
Did you try this:
options snd_hda_intel enable=1,0
This should disable the second card and avoid the above errors. Otherwise,
hopefully someone more familiar with this hardware and/or the
vga_switcheroo logic will chime in.
