My daughter's computer's sound recently has become very distorted. It's an\nEpox EP-8KTA2 with the VT82C686B integrated sound. I've swapped out the\nspeakers, the speaker's power supply, the wires, and another sound card\nwithout improving it a bit. I tried different VIA audio drivers. So,\nevidently it must be some sort of internal Windows problem. It's Windows XP\nProfessional with SP1. Any guidance appreciated. TIA.
