I did as you said, not being sure what sample rate I was recording at, I changed it to 44.1 and tried to record. About a minute in, I got an error saying I was not recording at the sample rate I selected and it asked me if I would like to change it. I hit yes, and it switched back to 48, AND IT STARTED WORKING!!! PTL, it recorded and saved the audio, even after shutting down.I don’t know what happened, but I am glad it did. Thank you , Brian
