Make sure you've included the proper firmware images.  Note the case.
We switched to a new firmware format for SI and newer and the firmware
files names are now lower case (new verde_pfp.bin vs old
VERDE_pfp.bin).  The older asics still use the old firmware format
with the upper case names.

As to the audio, I've never tested it on non-x86.  Make sure the hda
audio driver is loaded correctly.
