The problems are these options for snd-hda-intel.
enable_msi=1 should be OK, as long as it works.

But, single_cmd=1 is obviously not good.  This options is just for
debugging purpose.  That's why that commit hits.

model=laptop looks still needed for your device.  I'll add the quirk
entry if this model really works well.

So, just remove single_cmd=1 option and try again.
