So I checked and there is partial success. The audio now does come out via
HDMI. However, the 5.1 doesn't work.

It somehow thinks only 3 speakers are attached. And so F-L plays on F-L
speaker. Center plays on F-L speaker. F-R plays on F-R speaker. Rear-L
plays on F-L speaker and Rear-R plays on F-R speaker.

Pls help...!
