Run in the terminal:
systemctl --user stop pulseaudio.service pulseaudio.socket
This is because if we also want ATMOS it only works with alsa AFAIK and we have to free the sound card from pulseaudio, with pulseaudio I didn't have success with ATMOS files. Files without ATMOS seem to work ok with pulseaudio. Using pavucontrol, you have to change your HDMI profile to stereo only in the configuration tab, this is important, and then in the output tab, advanced arrow, you select what to bitstreaming, screenshot attached.
Going back to alsa, on your terminal now run:
mpv --audio-device=help and get your complete hdmi string. Look at screenshot attached
I tried each "alsa/hdmi:CARD=PCH,DEV=X" until it worked, mine was 2
in the terminal i used:
mpv --audio-device=alsa/hdmi:CARD=PCH,DEV=2 --audio-spdif=dts,truehd,dts-hd movie.mkv
(from mpv reference manual; "Possible codecs are ac3, dts, dts-hd, eac3, truehd")
And finally ATMOS. I'm very close to ditching windows
!! Picture of AVR showing atmos attached.
to go back to having pulseaudio:
systemctl --user start pulseaudio.service pulseaudio.socket
