Intermittent audio cutout over HDMI - Ubuntu 22.04.4

I'm getting intermittent audio cutouts on my machine. Audio will be playing fine but will then cut out for anywhere from ~0.5-5.0 seconds, then come back fine. What's interesting is that other sounds may continue to play just fine while it happens. For example, playing a game there will be background noises and music, but the dialog will just drop out a few words here and there while the background sounds and music continue playing fine. It also happens on "single track" audio sources like watching a video, so it isn't exclusively a multi-track issue.

This issue only started on my new computer that I built while keeping everything else the same (cabling, A/V receiver, display, etc.) Old computer was also running 22.04.4, so I suspect it might be something with the GPU in the new machine.

Trying to search for similar issues but I'm coming up with no good leads. The only one that looked like it may have been in the same realm suggested changing the refresh rate from 120hz to 119.88hz, but alas, that didn't work. Any suggestions for trying to narrow down the issue or some things I can try to troubleshoot?
