I had Optical Sound output working OK, I have dualboot on the machine.
It's a Abit IL-90MV board with Intel Chipset.
Sound was good, but all of the sudden after a reboot I get distorted sound, sound like a guitar amplifier set at full distortion. I tryed to rerun the Aduio/Video wizard, sound is distorted even in the wizard audio sample.
Please advice, it works fine in Vista and XP at the moment. There must be some issue with the Audio driver and/or some KDE sound daemon? Where are the configs? What should I look for?
Wow! Exactly same thing happened here! My Core/MD hybrid setup was working just fine with SPDIF through my receiver for last three days. All of a sudden tonight it started making only distortion .. it sounds like too much over saturated input signal (Scratchy, metallic). Initially I suspected a hosed motherboard. But when I put my WindowXP MCE hard disk back audio is working just fine. Confused :-(
The only change I made was adding a new USB/UIRT device. The problem persists even after I removed the new device.
