ok....no comment....it's impossible to mount the SB-Z on my motherboard: it hits the mb's heatsink.....the only thing to do is changing audio card?

Problem solved but there's another one....If I connect the SB-Z to my 2.1 by using RCA cables the sound is terrible! I nearly can't understand the words of a song the reason could be the bad quality of the cable? Or maybe some dust in the 2.1 RCA in?

It's unlikely that the cables are the problem if they worked OK before with the onboard audio.

Did you disable the onboard audio in the bios?

Before I was using optic fiber and for the SB-Z I bought RCA, I tried to change cable: problem fixed! That's strange because a cheaper cable works better. :S however do I have to disable "HD audio" on the bios?

Yes. You should disable the motherboard audio chipset in your bios. Generally, even a budget RCA cable will work fine, unless you bought THE cheapest cable you could find on the Internet. Then maybe you have an RCA problem. So best to troubleshoot some potential configuration issues first.

To disable the audio chipset in the BIOS it's enough to set "HD audio" to "disabled" or I must do something else?

Probably. You should look at your motherboard manual to make sure.
