I want to record sme old vinyl records using a USB turntable and software called Cakewalk Pyro. It usually works fine but some records top out too loud. Actually, I can adjust the recording volume using Windows Mixer. If I click on "Open Windows Mixer" from within Pyro and I get the message "There is a problem with your sound hardware. To install mixer devices go to Control Panels, click Printers and Other Hardware and click Add Hardware." Because I dont want to add any new hardware and only open Windows Mixer, I dont know what to do? Can anyone please help. Thanks.
