Audacity loosing audio devices setup and unable to play back or record when playing back recorded tracks: for this issue, I have sent the crash reports
The iTunes tracks are recently purchased and I drag them from my iTunes library to an open Audacity project which worked fine before. The audio devices crash also seemed to be fixed in earlier releases.
In general I am very pleased with the product which I use to record music podcasts.
Thanks for your feedback. The error occurs with recent purchases for which I have a quick workaround to remove any protection by converting the song to AAC.
