Hi, This is the first significant problem since downloading the beta, what is it 2 months or more? It's not stopped me playing sound as I've used the on-board system which has a similar spec. but it's frustrating. Vista SB X-Fi drivers certainly wouldn't work but I downloaded the recently issued Creative drivers for X-Fi in Win 7. Installed without problem and all indicators show a signal, eg sound level indicators etc. but there's no sound from my Cambridge Soundworks DTT 3500 5.1 Digital speakers. THERE IS SOUND on the earphones, which plug into the front panel. ??? The DTT 3500 system works with the High Def Audio on-board sound system!! Anyone had this and found a fix? Mike.
