Did you try to change audio device ?

#3

Try to upgrade to 2.1-rc2

I’m having an issue with lakka sound over hdmi on my odroid xu4. tried on monitors and tvs galore. I cannot change the audio device at all, and when through ssh command I try aplay -L my log only reads null discard all samples with no other entires. No luck so far and I am running version 2.1.1

I did however order the hardkernel usb audio adapter to see if that works any help would be appreciated. I would still like to use sound over hdmi if I could so I get sound from my soundbar which only takes hdmi and digital audio in.
