I decided to try a different audio CD player but was not impressed as it would not recognise my audio CDs in the CD-ROM although I could play them by opening a player first. Having uninstalled the program I still can't access the drive or autoplay audio CDs. When an audio CD is put in the drive a message comes up saying 'Access denied to drive, application or path'. When drive icon is clicked on it says 'drive not ready' I cannot understand what's changed to cause this problem. I don't have any problem with data CDs which will autoplay. The problem only applies to audio CDs. Checking a few tracks properties they all say they open with 'Media Player Classic' which the Player I normally use.
