i have a jetson nano. Audio dont work under DisplayPort, with HDMI i was able to play, but have enable the Audio Output every boot.
Please refer to this page.
I’m thinking there is still a question of where to permanently enable the HDMI audio…sounds like he has to enable HDMI audio every time he boots, but I am not sure where to permanently configure that.
For pulseaudio, it should be possible as describe here:
and the output sink names can be listed by executing …
$ pacmd list-sinks | grep "index:\|name:"
