Hi all, My setup has recently stopped working properly and I am out of ideas, any help would be v.appreciated Spec: Cubase 5 AMD Phenom Quad Core Processor Saphire Motherboard Realtek ALC662 Audio drive (not 100% on this) 8GB DDR2 RAM 500GB Hard drive Gainward GTS 450 Graphics Card When running a track, Cubase lags; clicks and crackles during playback. Also, looking at the mixer, there is a constant (small) signal going through the Stereo In.. It's quite odd, 80% of the signal is only going through the left channel. This has never happened before, my setup used to run very smoothly with no issues. Does anyone have any ideas?? Thanks.
