Stereo Tool

Hi

Been running ST for a number of years, however over the past couple of months we have started to have audio problems with the garbled audio, or audio that seems to slow up or down (like wow and flutter). I have replaced the PC, and the soundcard, and the only thing I can think that is significantly different is Windows 11 vs. Windows 10?

Here is a clip of what it sounds like https://humberwave.com/filez/clip.mp3 The problem starts and can stop fairly quickly, or can go on for a long time.

This issue occurs both on the uMPX output as well as the HD out which is feeding BUTT for streaming and DAB via VAC 4.7 lite. PC is an 11th gen core i5 with ESI24XL soundcard. I also intsalled the latest Beta yesterday to see if this fixed it,

CPU resource levels are not a problem, and I have run the latency tools on the machine. I cant find a problem! Any Ideas?
