I've manually crippled the code that enables the digital output
(commented out the following lines in patch_via.c at line 846 ish):
spec->multiout.dig_out_nid = VT1708_DIGOUT_NID;
spec->dig_in_nid = VT1708_DIGIN_NID;
This hasn't helped, beyond removing the last_cmd message from dmesg.
Back to the drawing board for me.
