Soundbar to PC issues

Hey everyone,

My current setup is the following:

TV: Samsung QCQ90S
Soundbar: Samsung HW-Q930D
PC having a 9800x3d and a 5070ti.

How's everything connected:

Tv - Soundbar: eARC.
PC - TV: hdmi from GPU
PC - Soundbar: hdmi from iGPU(only one hdmi slot on my GPU)

I had a lot of issues setting up dolby on my pc, and the current configuration was the only way I could do it. If I didn't plug the soundbar to my pc, my audio would randomly cut out/not work at all.

Right now I think I made it work, but there's another thing bugging me really bad. Whenever I change the tv source, to let's say the in-built netflix app, the soundbar switches to eARC(that's okay), but when I change it back to the PC, I need to actually use the soundbar remote to change the source from eARC-> hdmi.
Is there any way to make the soundbar do that automatically?

The TV settings are:
HDMI-eARC on Auto, Digital Output Audio Format(Auto)-> Tried passthrough but nothing changed.
Anynet+ is turned ON.

I'm literally at wit's end, as I tried yesterday to tinker with it(including that whole dolby fiasco) for a couple of hours, but couldn't fix anything.
Any tips would be appreciated!
