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.

Br, Kai
