Let me repeat my question: Does anyone know what would cause jerky CD-audio with newer 2.0 kernels (post-2.0.27)? I have ruled out heavy load on the system, checked for IRQ/IO/DMA conflicts, but I still consider the PS/2 mouse a possible problem (When moving the mouse around alot under X, it is easier to produce the error), but there must be something else involved, as the jerkiness is seen even after a fresh reboot, and running workbone right after first login...
Okay, maybe I'm smoking something, but my understanding of CD-ROMs playing CDDA consists of a program sending the appropriate message to the SCSI driver so that the "play" message gets sent across the SCSI bus to the CDROM. I am unaware of any further need for the program (or any part of the entire computer including the SCSI controller for that matter) to interact further with the CDROM to keep it playing. A cdrom player that shows the current time might need to do so, but to simply play this is unecessary. What happens if you quit your CD player program after starting the disc playing? Is your CD routed through your soundcard? If so, try routing it directly to your speakers or stereo by using the headphone jack on the front. Does it still skip? This may have to do with some use of the SCSI bus that is confusing the CD-ROM.. but it seems unlikely to me that a CDROM would be confused by signals sent to other targets. This jive with anyone else here?

Common Command Set. The canonical SCSI-1. This is because stone-age scsi was too extensible (read prone to incompatability). -josh -- To get out of this list, please send email to majordomo@suse.com with this text in its body: unsubscribe suse-linux-e
