[quote=enfleshjsc]I recently did a clean install of XP w/ SP2. I have already installed, uninstalled, and reinstalled the chipset drivers, Realtek HD drivers, and ATI drivers I'm not even sure how many times. Everything checks out OK in Device Manager (enabled and working properly). Onboard audio enabled in BIOS. Windows Audio service is started and set to automatic. When I open up "Sounds and Audio Device Properties" the default device (and only option) is 'Realtek HD Audio Input' or 'Realtek HD Audio output' as is appropriate, except for the midi playback which is 'Microsoft GS Wavetable SW Synth'. Volume is set on high and nothing is muted. But I still have no sound whatsoever, not even system sounds. Hopefully I'm not forgetting anything here. Below is my info from Belarc. Please let me know if you can think of anything that could help, as I'm about ready to start banging my head against the wall.
