Hi guys and gals. I've had some strange issue with my mobo HD audio recently. Randomly, the Realtek Audio would stop and appear as a High Definition Audio component with a Error Code 10 - device could not be started error in device manager. I've reinstalled drivers, checked speaker cables etc with no permanent solution. The only way to get it working again is to competely power down the system AND turn off the power supply and then restart it. Even with that patch job, im now getting crackling interference from the left and right speakers. Any ideas? Thanks.
