Hey guys, I have a USB Audio plug that goes to the amp box VIA USB cable. My computer is doing some annoying crap now. If i play music or a DVD the sound volume spikes and fades. Often times after several hours the song's may or may not play. the high notes will play but the ligher ones won't. Right now Windows Media Player will be fine playing my DVD of Hogans Heroes. But i had to adjust the USB volume up all the way, and my sound system is set to MAX. and the audio is barely audible. If i turn the USB volume down and restart the computer it will reset, 50% on the USB slider and volume level 14 (out of 31) will result is nice loud sound. Often times this gets so annoying when with classical music, it will spike and go from no sound to high pitched notes (of sound) back to silence. Is my USB port dieing? or is this a software issue? I should mention that i moved the USb audio from one USB port to another and the problem went away for about 3 months, and now its back. My right is on the left under system specs.
