Hmm. Your screenshot shows the program says "Media: Audio CD-ROM", so it obviously understands there's an audio CD in there. Other than saying 'unknown' instead of 'Audio CD' in the picture bar, is the functionality of the program affected in any way?

This occurs only in Ubuntu and not in Windows (dual boot). Tried multiple CDs. I also get the exact error on a USB Blu Ray drive.
