Fascinating but ANNOYING problem

[Kolusion]

I have just installed Ubuntu 10.04.3.

I have a problem where a high-pitched noise is coming through my 5.1 speakers.

My hardware profile is set to "Analog Surround 5.1 Output + Analog Stereo Input".

The strange and fascinating part comes when I get a browser pop-up message "Do you really want to close this window" - the high pitched sound goes away for a moment, but then returns.

When I set my hardware profile "Analog Surround 5.0 Output + Analog Stereo Input", the high pitched sound goes away permanently... but I have 5.1 and not 5.0, and as you'd expect.. I want to set my profile to 5.1, so I am looking to resolve this issue.


I have a Sound Blaster X-Fi XtremeGamer sound card.

I have double checked audio cables. Everythings fine.

The issue doesn't exist in Windows.
