Ah. that changes things a bit lol. However, as you said, it worked before installing ati driver...and when you installed driver windows would have taken ATI audio as default driver(this is what happened to me, both Vista and XP).

You must also make sure that windows has installed the updated codec for HD audio devices...there is a KB on it, but I cannot remember the number. Is your windows updated before driver install?


Maybe this can help you....


When i install windows, upon first boot i install DX SDK, mobo drivers(including audio and netwrok), update windows, and then install vid drivers. After installing vid drivers I had to go to audio settings and enable the ADI codec as default audio device, both in XP and Vista.


Did you take the same steps in the same order, or did you do differently?
