Yes, known. It is impossible currently (at least for me) to synchronize data requests with the wild, rigorous storm of audio IOCTL requests of those all-ressource-gathering-and-wasting audio CD programs (this is not meant to discredit xmcd). You simply can't do anything else on the drive cable if one of those big audio CD packages is running.
Solution #1: use a separate interface card for the drive you are playing audio with. It is safe to use one interface card for up to 4 data drives, and an additional interface card for (each of the) drive(s) you want to use for audio CD functions simultaneously.
Solution #2: use the cdtester utility for the audio part (appendix of linux/Documentation/cdrom/sbpcd); it is only useful for playing audio - f.e., trying to monitor the current audio position could cause the same hassle again.
