sticky volume control

The slider that controls the mic volume won’t stay put. I slide it over and as soon as I release the mouse, it slides back. If I go into Preferences and click on the
USB selection and click OK, that fixes it temporarily. As soon as I finish recording a track, I have to take this step all over again. Any suggestions?
Thanks,

It’s because the soundcard in your USB device iscontrolling the signal level - Adacity yields control to the USB device. Hence you moving the slider should have no effect on the recorded volume.

Some USB soundcards and some USB turntables have hardware gain controls to let you adjust the signal level - some do not. You haven’t told us which USB device you are using - so can’t offer more help.
