If you use an external SCSI CD-ROM drive, or if you have two CD-ROM drives and one of them doesn’t have a direct connection to your sound card, you can still listen to audio discs in that drive by using the cdda-fs driver. Just mount an audio CD and drag its corresponding WAV tracks (or the entire WAV folder) onto your audio player of choice.You can literally have as many concurrently running CD audio streams as you do drives.
