Excuse me if this is common knowledge:
I was under the impression that the only way to listen to Audio CDs was by running the audio through a sound card but using AsimCDFS audio (ASIMTunes) player program there is an option you can select Audio Through Amiga Hardware. I did this and listened to some fine Rockabilly on my Amiga 2000. It does recommend an accelerator due to the conversion load but it works! Now it is my most expensive CD player.
