OK, I am not an entire novice at this computer thing. So I was having what I call a disturbance with the on board sound system and decided to install a Sound Blaster Audigy FX, MOD SB1570. I was told that the card works with Win 7, 64 bit and it also says that on the box. So I remove the Realtek HD audio program, shut down the on board Realtek in he BIOS. Install the SB card and restart the computer. No doubt Win 7 starts to search off line drivers and etc. I insert the CD/DVD rom that came with the card and all installed just fine. BUT I get no sound from the card. I tried everything that came across my mind, even some other style speakers I have for testing friends system. NO SOUND. I am at my wits end. And since all of the MB manufactures and Sound card people are all of for the Holiday weekend....can't talk to no one. And one have ANY IDEAS....if so it would greatly appreciated.
