If I go to VLC I need to go to Audio > Sound Device and select the second option, ie HDMI strero. Then the sounds play in VLC through the HDMI with no problem. But still not from openplotter.
I have edited /boot/config.txt
and set
hdmi_drive=2
but that did not help.
If I switch back to my RPI 3, all is working fine. I have compared settings on the two as best I can, but see no differences.
Where do I start looking?
I am guessing that somewhere I need to point the default sound output to the first HDMI slot?
Thanks
I had issues where the sound jumped from one adapter to another so what I did is excluded the channel I didn't need. I did that using a # or removing dtparam=audio=on in config.txt.
Also try
hdmi_drive:0=2
hdmi_drive:1=1
Hdmi 0 is the one next to the USB-C port
I was facing the same issue and can confirm that putting a # before dtparam=audio=on did resolve the issue
