My system has been running, recording 12-16 tracks simultaneously without any problems for about a year. Within the last week, when opening any sessions I had previously recorded, I get clicks and pops on playback. If I solo the track in Cubase, I still get clicks and pops. If I close Cubase and play a single track in windows media player, the track sounds clean, so it appears I don’t have any damaged files (hopefully). Tonight I tried recording some new tracks, to see if the system would actually record the clicks and pops “to tape.” It did. If I play a single track in WMP, the tracks sound dirty. Now, I have made ZERO changes to my system in the last 3 months: same computer, memory, hard drives, hardware, software, plugins. Nothing has changed. Does anyone have any thoughts on why I would suddenly be getting clicks and pops on both input and output? PC: 3GHz Pentium 4 512Meg Ram (has recorded fine for the last 1+ year; 1GB on the way ) 80GB system drive, SATA 200GB audio drive, SATA Windows 2000 EMU 1820M interface Running Cubase VST (5.1, I believe) Things I have tried: -Made sure the drive controller is set to “UDMA if available” -Set the computer to be optimized for “background applications” (to service the audio capture) under the System menu->Advanced tab->Performance -Tried increasing latency from 10ms to 100ms. This seems to help, but why should I have to increase it by a factor of 10 if my system hasn’t changed? It still has problems at 50ms, and perhaps even at 100ms (haven’t tried recording at 100ms) -Unloaded plugins that have been installed 6months+ -Running test application from hard drive manufacturer: comes out OK -Disabled/enabled Hyperthreading. When disabled, the problem is much worse. My suspicion: for some reason or other, my audio drive is “suddenly” not working up to speed. It has worked fine for over a year, but now seems to operate slowly? Why the change? It does seem to operate with some level of success, since I can still hear the audio files on playback, it just doesn’t seem to be serving them up fast enough. Does anyone have any thoughts on what the problem is? I would be happier to know what the problem is and fix it (i.e. new hard drive) than to just start replacing parts and see if it helps. That could get expensive really quickly. Any help is appreciated, thanks.
