Hi,

I am trying to force the EDID on my setup but I can only seem to get one working. I followed fritchs' vaapi guide (with some modifications) but it doesnt seem to work for both outputs. Note, my setup is 2 video outs: 1 hdmi directly to tv and a 1 dp++>passive adapter>hdmi>avr>tv. The hdmi directly to the tv is for the video and the avr is just used to audio.

Code:

for p in /sys/class/drm/*/status; do con=${p%/status}; echo -n "${con#*/card?-}: "; cat $p; done
DP-1: disconnected
HDMI-A-1: connected
HDMI-A-2: connected

Not sure what else I can provide, but if somthing is missing please let me know.
Any ideas?

Got it! The boot options syntax was wrong. I should have RTFM  
Need a comma between the two values (with no space!) and no second drm.edid_firmware tag:

video= needs two tags though.

Great, audio switching is working perfectly now
