ASUS G50VT + Creative X Fi USB

[Vendramini]

Hello,

My X-Fi USB Sound card is working until I play one song, after that, it stops completely. I just plugged it in the jack and it starts to work.

Fedora 14, all up to date.
Tried on Amarok and Rhythmbox. Both got the same error.

What should I do? Is there some drive? I really tried google and I found some URLs with drivers, like this:
http://exaudio.sourceforge.net/k26.html but I didn't need it to work.

Thanks,
André Vendramini
