For a long time now, I've had audio drops and sometimes even keyboard input drops through my KVM switches.
When a drop occurs, all audio across all applications drop at once. If there's a video playing then it'll pause briefly. In a game, I just miss a second of audio with no video stuttering.
When I connect my USB speakers directly to my motherboard then the issue does not occur; only through the KVM switch. I was using this decent switch I got off Amazon but just replaced it with one from Level 1 Techs and the issue remained. I've tried different ports on the switches and my board as well.
The issue also only occurs on my Linux computer. When I switch over to my work laptop running Windows I don't have the issue.
I'm not seeing anything in journalctl that seems related after swapping KVM switches. With the old switch I was seeing logs like below but no longer see that with the new switch.

My neighbor was having issues with his PC freezing up during games, saying his CPU fan specifically) would ramp up. He then bought new parts and asked me to build him a new PC to replace it which I did (we exchange handiwork). Now he's wanting to give his old parts to a friend of his who had an even older PC. So I've got another build which was mostly parts from his old one with the exception of a new power supply and graphics card.

At first, 3/4 of the time I wouldn't get any video. I noticed he had two different sets of memory so I stress tested each set individually and in each of the DIMM slots. It all tested fine and I was getting video more consistently when only using a single set. I was using stress to test both the CPU and memory and never came across any freezing or other issues.

I've tried going into BIOS to see if any settings in there were causing issues with the mixed memory but regardless of the configuration or using the on-board graphics, I get no video in BIOS.

Now, regardless of configuration, I'm getting no video in BIOS or an OS 100% of the time.

I'm looking for a Low-Profile PCIe Thunderbolt 4 card. I'd settle for Thunderbolt 3.

I have a Hyte Y60 case limiting me to only low-profile PCIe cards except for the verticle mount slots for the GPU.

I also have an Asus Prime X670E-Pro Wifi motherboard which is kinda weak sauce but would support a thunderbolt card on the PCIe 4.0 slot and has a TB_Header.

I've seen some cards that would've been good but not sure on compatibility. Like one I saw from HP had a header that was 2x6 Pins and the header on my board is 13 Pins in a 2x7 configuration. I think that one was specific to HP workstations.

Then I also see cards that don't have an internal header and don't believe they'd work outside of their intended products, like the QNAP NAS

For a little over a month now, when playing videos on firefox, VLC, or any other application, I get infrequent stutters. This is with or without hardware accelleration. It's as if the video pauses briefly. If multiple videos are playing, even across different applications, each of them will be effected at the same time.
