Audio delay completely out of no where. High end PC.

[AsukaoYL]

Been using OBS for YEARS absolutely no issues. I recently built a new PC and Its been completely random. Just today I noticed all my gameplay recordings had a decent audio delay. Never had this issue with my old PC. Pushing it to the limit as well. Recording while doing 5 more system intense things with zero issues. Gaming, recording, editing and rendering at the same time for example. Its also seems like it is completely random when it happens and when it doesn't. Sometimes it happens while doing replay buffer, sometimes it doesn't. Sometimes it does it while recording sometimes it doesn't.

OLD PC
Windows 10
AMD RYZEN 9 3900X
3080 TI
GIGABYTE X570 AORUS MASTER
32GB RAM

I never had an audio delay with my old pc. Pushing it to the limit as well. I was recording gameplay in 1024, Rending video in Davinci Resolve in 4K, Recording a zoom call and sometimes even gaming while also recording. All at the same time with no delay.

NEW PC
Windows 11
AMD Ryzen 7 9800X3D
5080 Founders
MAG X870E TOMAHAWK
64GB RAM

Completely Random delay anywhere between 200ms to 32ms so the off set is not realistic as I wont know till after the fact how delayed the audio will be. Recording in 2K is the only difference and not doing anything else in the background. Yet audio delay is present..

The Capture Interference in the log with delay was me trying to change audio inputs from mixer to added mic and headphones to sources rather mixer to see if the problem was fixed. The delay existed ether way.

Max Audio Buffering exists in every single log regardless if there is a delay or no delay.

Been trying different encoders as well, sometimes a encoder has no delay sometimes it does.

Its absolutely been driving me crazy.

OBS isn't causing your Desktop Audio to lag. Your OBS set-up looks OK. Audio lag can be caused by system overload.

Are Windows Audio Enhancements & Spacial Sound disabled? It's a new rig, maybe the audio driver needs some attention, have you checked your mobo's support page?

22:49:01.610: Source Desktop Audio audio is lagging (over by 37043.72 ms) at max audio buffering. Restarting source audio.
22:50:00.575: Source Desktop Audio audio is lagging (over by 23518.89 ms) at max audio buffering. Restarting source audio.
22:51:21.619: Source Desktop Audio audio is lagging (over by 77834.44 ms) at max audio buffering. Restarting source audio.

I flashed the motherboard when I built the PC to the newest driver. I have the MSI Tomahawk x870e

I understand this might be a system overload but how is that even possible. It cant be the actual specs, I mean my old PC is so much worse and I truly pushed that system to the max.

Windows Audio Enhancements is Device Default Effects, Should I turn this off?
Spatial Sound is Disabled

Its also completely random. For example I have done nothing and the past 2 days NO Delay.

What is your suggestion on troubleshooting this?

Yep, disable the audio enhancements & see if the lag ceases.

Also, disable Game DVR while you're at it. It's not needed so get it out of the way.
