Something else I have experience happened when I moved the Digirig to another USB port on my laptop computer running Win 11.
When I restarted VARA FM the VU meter audio level appeared to be connecting then disconnecting.
Right click the Windows icon then select System> Sound> You may notice the Windows Digirig ID has a number behind it indicating a 2nd installation.
Scroll down to mic audio. Select OFF under the normal audio enhancements button. This turns OFF the auto gain for the mic input.
That is what caused the problem.?
