Try downloading and installing the latest (non-beta) driver from the Creative website. Use Driver Sweeper to clear out all old Creative entries.
The driver works for almost all X-Fi cards. You do indeed have the Extreme gamer card and not the Extreme music card. I too thought I had the the extreme music card for the longest time on my XPS 420 but recently found it it is the gamer. The new driver will help reduce or eliminate your SOD for most situations.
If you have dual video cards try disabling SLI.
Has anyone solved this issue yet?
Which driver should I have installed for my system? If I go to the Dell drivers support page on the web, there are NO xifi drivers for an XPS730 - the only drivers I have are the ones supplied on the CD when I bought the computer in May 2008.
Is it safe to follow the link posted in this forum and install the xifi driver on an xps730 even though the dell support page does not list it?
Maybe this has something to do with the X-fi SOD?
This is how my machine sounds while playing any sound, except directly after reseting in creative console launcher: http://cid-0c299fb836333537.skydrive.live.com/self.aspx/Offentlig/L001.WAV
Hmm, after testing for a while: with the new 2.15.0006 driver, and with "X-FI CMSS 3D" deactivated it´s get´s better. Both the problem in my previous post and the SOD.
But insted i get another SOD, and the computers sound crashes and i have to reboot to get sound. Seems to me like the CMSS has something to do with the SOD. The SOD II sounds more like a radio not tuned in propely and is over after a second or two.
Could anyone else please try to disable CMSS and see what happens?
And does anyone got proper sound with creative console launcher in 5.1 mode?
