Well, sometimes, but not often.

I get the "repeating last sample" also (good way to describe it). This may be unrelated, but I also found out that the sound driver isn't happy when the card shares its IRQ with someone. The Dell Precision has an onboard SCSI controller that by default shares an IRQ with the sound card. Even with no SCSI disks connected, the sound would be really choppy. When I disabled the SCSI controller in the BIOS, those problems went away. Lars -- Lars Eggert <[EMAIL PROTECTED]> USC Information Sciences Institute
