Hi I am getting the "no speakers or headphones are plugged in" error and the red x over the audio icon. When I check the volume control options I only get ati hdmi output as an option and not the mobo's on board sound card. I have checked this on the Internet and tried updating my drivers including the realtek ones. I have also enabled the HD sound in my BIOS even though it was not disabled (it was on auto). I am not shure what to do now. I have the ASrock mobo N68C-S USS with an Athalon II 640 and ddr 2 667 memory (2gb). My gfx card is the ATI HD 5770 and I have no dedicated sound card. I am running win 7 64bit. So any ideas?
