No audio over HDMI

Hello,

I know this has been posted many times but none of the posts seem to have the solution to the problem I’m having. I’m unable to get the audio to play out anything but I specifically want it to play through hdmi.


aplay -Lnull

This is what I when I generate a list of soundcards using aplay but when I use the “audio_device” command I’m met with this message

-sh: audio_device: not found

setting the soundcard manually in the retroarch config file seems to have no affect either.

Did you try to put in the configuration file /storage/.config/retroarch/retroarch.cfg

audio_device=hdmi:CARD=NVidia,DEV=0

or

audio_device=hdmi:CARD=NVidia,DEV=1

Before editing you need to stop retroarch :

systemctl stop retroarch

edit the file (CTRL+O then Enter to save then CTRL+X to exit)

 nano [FONT=arial]/storage/.config/retroarch/retroarch.cfg

And then restart retroarch

retroarch

Yeah that’s the first thing I tried.

Can you try this ?
