I recently got my hands on an Onyx 350, with an IR3 with a DG5-2 / TVO.  However, I'm getting no output from the DG.  Running `irsaudit`, I get some failures related to the VOC registers:

DIAG                Replace DG board; BEFORE replacing any ASICS, ensure clocks
DIAG                  on the DG are running properly (like the VOF clocks for
DIAG                  VOC failures).  Faulty or not running clocks _will_ cause
DIAG                  VOC failures.  Otherwise, repair by reworking flawed
DIAG                  ASICs.


It's oddly only managing to read the low halfword of each 32-bit register; upper halfword seems to be zero.  Anyone have any suggestions?  Or any notion of how to ensure "clocks on the DG are running"?
