muzbox wont record

For many years I have used audacity to record my vinyl albums from hifi onto my pc. I’ve just got new Acer pc and downloaded Audacity 3.1.3 onto windows 11 home edition.
my microphone hasn’t changed, usb muzbox using the line out from my hifi. When i set audacity to record it does that for about half a second then stops recording. Audacity carries on even though the waveform has disappeared.
so far as i csan tell all the permissions in windows are set to access thw muzbox.

can anyone solve the problem for me?

many thanks

Make sure [u]Windows Enhancements[/u] are turned OFF. (Audacity doesn’t monkey with the audio data while recording but sometimes Windows does.)
