Before I start chasing things - ie RTFM - should the HDMI feed from a
graphics card also be capable of carrying system audio? On Win10, if it

For digital audio, if an HDMI device has audio, it is required to

1.3, HDMI allows lossless compressed audio streams Dolby TrueHD and DTS-HD
Master Audio. As with the Y'CBCR video, audio capability is optional.
