I started getting this error when trying to do loopback recording, only after installing the Arctis 7 software a couple days ago. Before the install it was working fine. That being said, earlier in the year it was not working again (same error). I checked the sample rate in both Audacity and in the Windows sound device settings to make sure they matched. Tried changing both from 48000 to 41000 with no luck.
I’m on Windows 10. Not home right now so I cannot check the version number, but this likely would have been the version from about a year ago.
