Can't get rid of audio static with capture card

Whenever I record from a capture card, I have intermittent audio static or what sounds kind of like a lag or skip in my recordings/streams and the monitor&output. I don't really see any video stuttering, but there's a very small blip in the recording linked below. I'm pretty sure it's just an audio issue but I'm not sure if it's overall performance as well. If I'm only listening to the audio coming out of the monitor I'm playing on, both with and without headphones, I don't hear any static. Other games I capture directly from windows be it desktop or game capture etc. never has problems. My PC speakers don't have any issue like this with any other audio. However I managed to fix this on my Surface Pro 7 by turning off "use custom audio device", but this doesn't work on my PC. Also I want to stream from my gaming PC, not my Surface Pro which has much lower specs. I've tried everything:
  • Putting the USB cable in the proper USB 3.0 port (This helped a lot but didn't remove it. Doi.)
  • Trying different cables including USB C and different ports
  • Trying a different HDMI cable in the output
  • Trying a different capture card
  • Trying a different recording software
  • Reinstalling OBS/removing and re-adding all my sources
  • Updating OBS and Windows
  • Tried a bunch of different settings
I don't know what may be causing any interference or anything with it, or what's different about my Surface Pro. I compared all the settings and they're both pretty default before messing with them more to no avail. Maybe something with AMD Software Adrenalin Edition? IDK. I should also have similar antivirus settings and programs on both my surface and PC. I do have old Huion tablet drivers, but I think that only effects video not showing up, not something like this.

Specs:
OBS version: 30.0.1 or something on my Surface, 32.1.1 on PC (Can't remember PC version prior to update, both ver. give issues.)
Windows 11 version 25H2. Can't remember version prior to updating (I usually pause them as long as possible)
Trying to capture from Nintendo Switch 2

Capture Cards: Tried Fifine V3 and the Acer 3.0 USB thing. Both give same results.

Any help greatly appreciated!
 
One more thing I just noticed: If I deactivate the Video Capture Device source, the seperate audio input capture no longer has static. It's only when the video is enabled.

My PC should be pretty strong so I don't know why the video would make it lag up like that. Adding a desktop capture source doesn't cause it to get staticy, it's only when running the video capture device source. I did also try doing audio and video from the single video capture device source but that gives the same result with static. Don't know if this info helps.
 
Last little things (sorry I'd edit the post if I could): I swapped to the MJPEG video format and it improved quite a lot. Of course the color got all weird but I edited it a bit to be pretty close. I also added 1ms sync on the audio but idk if that actually makes a difference or it's my imagination. I still don't know what it is where having the video active makes it sound like that. The same goes for "listen to this device" in windows. It's completely fine until I open OBS and the video capture is going. I'm not really sure if I can fudge some kind of workaround with this but this is the best I can get it for now, but there's still some static. Just much more minimal.

I'm beat. Granted both capture cards I tested with were $25-$50 and IDK if I'd have better luck if I just dished out for a 100+ dollar one, but it looks like even those have issues and it'd stink if it ended up having the same problem. But as I mentioned it's weird it works just fine with something like my Surface Pro but not my gaming PC.

Again, any suggestions or ideas for a way to work around this are welcome!
