My TV only has issues with audio with some modes - luckily ones I don't need.

You could try changing modes with xrandr.

One complication is that not all of them are likely to be listed with xrandr
--verbose, but they should be in Xorg.o.log so you can add them using xrandr
like -

xrandr --newmode "1080p24" 74.25  1920 2558 2602 2750  1080 1084 1089 1125
+hsync +vsync
xrandr --addmode DVI-0 "1080p24"

This is just an example for my tv - you'll need to change the connector name
and mode timings (listed in Xorg.o.log) to match yours.
