--- Comment #7 from Peter Wu <peter at lekensteyn.nl> ---
Possibly interesting information from
https://devtalk.nvidia.com/default/topic/609790/no-hdmi-sound-w-optimus-in-linux/

On Windows, the audio device is not visible normally, but when a HDMI audio
cable is inserted, suddenly the audio device appears. Perhaps the Windows
driver is doing some rescanning automatically?


Related: 20/111 Nvidia devices report an audio device. AFAIK newer machines
have their HDMI port connected to the Nvidia card, so something is probably
missing there. See
