i'm rather new to the world of digital recording...having two learning curves to master:The PC and Sonar xl. i'm running sonarxl w/A7V333MOTHERBOARD, 1gig athlon, win 2000 pro and 528 megs DDR333 SDRAM, Edirol ua-5 sound card. i'm getting good results experimenting with different latency settings etc. the problem? it seems I can't stop random clicks and pops from creeping up in the track. The input/gain is low, latency settings don't seem to help. also, when i click on "play' or "stop" i hear an audible pop. this makes auto punch impossible. no other programs are running on my system and everything runs great otherwise(no drop outs etc.) Would a dual processor set-up eliminate the problem? Faster hard drive? more ram? Does various "de-clicking" software work? Sonar recommends disabling ACPI?(but they seem to suggest that for every problem) then, the tech guys at my computer shop just raise their eyebrows at that suggestion disabling ACPI?hmmmmm. Do I just have to live with the clicks? Love the digital flexibility, hate the eternal system tweeking that sucks up valuable creative time. What's the secret to a stable system? any help would be greatly appreciated...
