Ozzy05, Go to the link below and click on the "?" to the left of "Where did my Sounds go?" to expand it and you'll find several possible solutions.
Hello folks,just recently experienced a no audio problem on my computer. Originally had a c-media card installed with everything working ok , then suddenly no sounds at all. Removed card and installed spare Sound Blaster Audigy and downloaded latest drivers. Everything installed ok. No conflicts in Device Manager, proper card identified in control panel/sounds. Windows sound on reboot , but after reboot nothing again. After countless removal of sound card in Device Manager and re-installing drivers , no change. Removed card and re-verted back to on board audio. Realtek high definition audio with latest and original cd AC-97 drivers. Now no audio device available in Control panel/sounds. Within the Realtek HD Audio Control panel I can test speakers and hear sound ok.
