After I installed BiaB 2021 onto my Internet computer it ran perfectly. I use the motherboard Realtek chip on this computer.

But when I installed 2021 onto my music computer I had terrible latency. 2021 changed my audio interface from my Roland Octa-Capture to the Window's sound chip. It also changed my drivers from MME to WAS. Once I changed back to the Roland all was OK.

Also I have had Window updates change my audio interface from the Roland to RealTek. Adding to Trev's device manager advice be sure to check that Win 10 didn't activate the Realtek sound chip as that can also cause problems if it is on at the same time as external audio interfaces. Deactivate the Realtek if it is on.

Hopefully this will help. Good luck.

I guess Do You Hear What I Hear was a bad song choice!
