This is kind of related to my other post ([4.2][PC] Sound Output) but the hardware in question is playing sound from the device rather than the screen’s speaker. The cable being used is a Display Port to HDMI with the Display port on the device end. Output of aplay -L is shown below.
So far, I have tried “default:CARD=PCH” and “hdmi:CARD=PCH,DEV=0”. As the port at the back of the device is Display Port, should it list this instead of HDMI. There are no HDMI’s on the device (only the screen). Any advice on this much appreciated.
