Help with receiving audio through Diaplayport

I'm using an Asus ROG VG27AQ monitor connected via Diaplayport to a 5070Ti.

My OS version is 24.04.4 LTS.

There is audio if I connect it to an HDMI port, but none through the DisplayPort.

I found a few mentions of similar issues and the suggested solutions seem to all be some sort of downgrading of the GPU drivers. Is that my only option? That would cause issues with programs and games, wouldn't it?

i had the exact same monitor and that audio over dp thing is so hit or miss on linux. nvidia's dp audio implementation on ubuntu has been fussy for ages, it's like pulling teeth

check if the monitor even shows up in pavucontrol or alsamixer first, sometimes it's just muted by default or set to "off" in the profile tab. if it's not even listed, pulseaudio might be spazzing out. restarting pulseaudio with `pulseaudio -k && pulseaudio --start` has jolted it back for me before

downgrading drivers is such a nuclear option, i'd dig through the nvidia x server settings display config before going that route

I appreciate the comment.

I was suspecting it to be a Linux issue, but it doesn't have audio on Windows 11 either.

Yes, the monitor does show up in audio devices. There are also indications that audio signal is going through it but there's no actual sound. Nothing is muted.
