I am at my wits end. I recently upgraded my sound card and hard drives and am having trouble while recording. The palyback is stuttering and skipping while additional tracks are recording. This happens even with one track playing back and one track recording so it does not appear to be a cpu issue. When playing back without recording, it is fine. My system specs are: Asus A7N8X-E mother board AMD XP 2800+ CPU 512 MB PC3200 DDR Ram 2 - Maxtor 10k RPM SCSI hard drives (one applications / one wave files) RME DIGI9652 sound card ADAT LX20 interfaces to computer Sonar 2.0 XL Win XP Home Ed I have followed suggestions from the forums about tweaking Win XP and still no help. I have temporarily fixed it by monitoring through the MB sound card while recording, but this puts a slight delay on the new tracks. Is the RME card not a full duplex card? Any help would be greatly appreciated. Thanks.
