I'm at a loss here... 10 years ago I had a Dell straight from the factory. When I plugged a guitat into a preamp and ran it into the line in on the MOBO, I was able to record audio and monitor it in real time using the Acid 4 software. Fast forward to today. I have Acid Studio 8, and I am looking to record some audio. However, there is significant lag between the preamp and the computer speaker output. You can hear this by turning on the click on the preamp and comparing the headphone output of this unit to the speaker output of the PC. (tick-tock... tick-tock... sounds like 2 metronomes running, not 1.) My setup is bare bones and as follows: Windows 7 Home Premium 64-bit *All updates ASUS M4A79XTD EVO Motherboard AMD Athlon II X4 630 2.8GHz Socket AM3 95W Quad-Core SAPPHIRE 100293DP Radeon HD 5570 1GB 128-bit DDR3 PCI Express GeIl EVO One (3x2GB) DDR3 1333 Main Drive is a SATA 250GB Seagate Secondary Drive 1.5TB Western Digital OCZ Fatal1ty 550 Watt Power Supply I took it to a PC magic-man to "tweak" the BIOS settings. As of 45 minutes ago, I am $65 poorer with the exact same problem I have been trying to fix for months. I am not opposed to building a completely new tower that is specifically built for recording - but I'd love to fix this one if possible. Perhaps the steps we take will lead to a new system. What am I doing wrong? (I had an internal soundcard installed (Creative X-fi) but I pulled it, because it gave the exact same results.) Thanks so much for any and all help.
