succo Posted January 1, 2021 Posted January 1, 2021 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 1
Werner Posted January 1, 2021 Posted January 1, 2021 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 .
succo Posted January 3, 2021 Author Posted January 3, 2021 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
aprayoga Posted January 4, 2021 Posted January 4, 2021 @succo what image/kernel did you use? on legacy it should work. I haven't tested much on mainline kernel.
succo Posted January 4, 2021 Author Posted January 4, 2021 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
