Audio cuts in and out after upgrading CPU

Hello,

I recently upgraded my CPU and now I have audio issues in OBS. Audio from the capture card will play for a second or two and cut out for long periods of 30 seconds or more, play for another second, and then cut out again. In recordings the audio input from the mic and the desktop are audible, if a little bit crunchy. Very little audio is recorded from the video capture device.

I have tried: updating drivers, made sure all audio devices on 48, software encoding, hardware encoding, switching USB ports, rolling back to v.29, reinstalling OBS and all presets, and switched audio devices.

The video looks great, no stuttering or lag.

In the meantime I've been running the system through my laptop instead of my PC with no audio issues, but since the graphics card is considerably worse on my laptop the video is not great for streaming or recording. But at least I can play the game.

I've included a copy of the log and analyzer, which says that I have insufficient hardware even though I just upgraded my CPU and had no issues with my old 4th gen CPU. It also suggests using hardware encoding, which I am indeed using.

1. Insufficient hardware because you have i3 and requirements are i5.
2. Run OBS as Admin. To run OBS as Administrator, right click on the OBS shortcut, properties, advanced, check box, ok, apply, ok.
3. Is this missing audio visible in the audio mixer?

Yep, it needs an update as it clearly doesn't know the difference between Gen 2 & Gen 12. FWIW, that CPU is just as powerful as a i5 10600.

Oh thanks, it's a little better running it as admin. Still cuts out rather often, especially after a few minutes.

Yes, the missing audio is visible in the mixer. I can see the levels drop when the audio cuts out, and I can see them come back up when the audio blinks in.

Log is incomplete. Audio routing needs improvement. You're using both Global & Source Audio, should be one or the other not both. Sample-rate mis-match, plus "Use Device Timing" has been assigned to multiple devices. Last line below, Video capture device is lagging.

Seems to be some issue with the capture device for me. Did you also change the USB cable? As far as I read the capture card's manual, it wants to be plugged into a USB 3 port with a USB 3 capable cable (blue colored plugs).
