is there any way to send audio through displayport? i installed kodi, just as a database updater, but it fills the log with errors related to the audio system, and i see that aplay doesn't show any audio device, so another question is, is there any way to emulate an audio device?

 

thanks

In theory DP allows carrying audio signal but tbh I have my doubts that there are proper driver in existence that can make use of it, especially on hardware that is not x86/amd64 mainstream .

ok, for now i solved the errors using the snd_dummy driver, but, afaik, audio over usb-c works for the nanopi (which is rk3399 as the helios) so maybe it could work here too

@succo what image/kernel did you use?

on legacy it should work. I haven't tested much on mainline kernel.

it's Armbian 21.02.0-trunk.54 Groovy with Linux 5.9.16-rockchip64 right now

i used a daily build with sources.list for devel, so I am running hirsute (rolling)

and no audio device is created with usb-c hdmi dongle inserted

btw, sorry for the late reply, but i'm an armbian forum beginner, so can't post more than once a day
