I doubt the audio parameter would affect anything in this regard, but you said
it was required for the board to work properly?  Is that the case or am I
misinterpreting you?  For audio on your board, you need to enable DC which is
only available on kernel 4.15 and newer.  You can boot with amdgpu.dc=1 to
enable DC.  The msi option may help narrow down the interrupt issue.  If it
helps, it seems MSIs are not working properly on your system after resume. 
This would probably be something outside of the driver if it's a regression.
