Its a separate device from the internal soundcard and Windows will only allow one at a time. To change from one to the other, you need to go into control panel--> sound And choose the Ati card output and make it the default device. If you have done this, and the TV is still cutting out at times you really need to consider if its a problem with HMDI audio input on the TV or the card? Replacing the card may just lead to you finding out your TV's broken.
