Audio lag/stutter

My setup has been working well previously. Somewhere between ChimeraOS 37 and now I’ve developed stuttering/lagging audio (I was away for a while so I’m not exactly sure when). Occasionally it sounds as if the audio slows then speeds up to match the frames on the screen.

There might also be some video lag occurring at the same time but this is not as noticeable as the audio issues.

Happens in BPM and in GamepadUI. I’ve also opened a browser in desktop mode and I’m getting similar issues when playing videos through there.

Nvidia Geforce RTX 3050 8Gb RAM with audio out through HDMI,
i5 12500
64Gb RAM

Happens regardless of whether the system is loaded. Can’t see any usage spikes in top and nvidia-smi isn’t giving any clues.

Any help would be appreciated.
