Conflict with audio drives

[antonio20001]

I have a big problem with Ubuntu:
when starting TS, if i have an application that use audio drives (for example an mp3 reader like VLC) the ts's audio don't work, i can't hear and speak too.
Else, if i start it with not these programs, i can speak and hear ts's sounds(like Link engaged) and players voice, but i can't listen to other audio!

Here is my computer configuration:
Acer Aspire 5920g, version with ati.
All the computer specs that you need can be found by internet..
OS: Ubuntu 8.10 x64 version, all the drivers and upgrades installed.

Can be a drive problem? Or a TS problem? I see a lot of ubuntu users with the same problem. But i think i'm more specific.

I was thinking it might be a driver issue until I found this http://ubuntuforums.org/showthread.php?p=4131206

Hope this helps, found it with google. :) The last post in that thread gives a reason why this happens.
