thanks for the test.
From the test it seems that it can work well if audio is disabled in HDMI.
But from the EDID we know that the audio block can be found in extension EDID block and it is supported by HDMI monitor.

Will you please try to switch to another resolution and see whether the issue still exists? Please use the following command to switch to another resolution(1920x1080) .
    a. Add a new mode.
             xrandr --newmode 1920x1080 148.5
                1920 2008 2052 2200
  1080 1084 1089 1125
  "+HSync" "+VSync"
    b. xrandr --addmode HDMI-2 1920x1080
    c. xrandr --output HDMI-2 --mode 1920x1080

Will you please also attach the register dump after changing to 1920x1080?
Thanks.
