I just upgrade to windows 7 from Vista. everything works fine except i don't have any audio. I am using sharp HD TV as output and using HDMI cable.what should i do??Thanks

Do you have the right output device selected? I know that Vista seemed to select the right one for me (or at least the audio driver did), but it doesn't seem to in 7. Right click on the volume control, select playback devices, and set what you want to use as your default. It sounds like you'll want what is the Digital Output Device on mine, but I don't know if that's a 7 thing or a driver thing, so.

Thanks ! I did that already. Not working. I think it's more like a driver thing. Anyone usinga HDTV as output device and have the same problem?
