I’ve been using Audacity for recording without a hitch for years.
Yesterday I was in a new program of mine - Sony Movie Studio. I wanted to edit just the sound track. When I chose “audio editor” a popup asked me if i wanted to go to my audio editor. I selected yes. The program loaded Audacity and started Audacity automatically!
The next day I went to record something with Audacity and up popped an error box “Error while opening sound device. Please check the recording device settings and the project sample rate”. I re-installed Audacity and chose default preferences. I’m still getting the same error message.
Any ideas how Movie Studio screwed up my recording capability?
