Sound Card Latency + RANT

I just bought a brand spanking new Dell XPS 8900.  My intention is to use it to record realtime audio via a Line 6 UX2, a software driver sound processor specifically for recording).   When i tried it initially there was a delay in the sound creation and the sound coming from the speaker.    I called Dell support, got shuffled around a bit, and found someone who solved the problem by repeatedly installing the Sountec Drivers.    Well, for some reason, (I suspect perhaps a Windows Update??),  when I tried it there was no sound coming from the UX2.  I had to reinstall the drivers for the UX2 and I heard sound but the latency was back.   I spent 2 hours on the phone with Dell support.  I spoke to 5 or 6 different techs who seemed to only want to transfer me from hardward to software support and back again.  The previous time that I got this solved was not nearly as painful.  I was told that my NEW Dell Computer was not covered for this type of issue and that I would have to purchase additional services to get it repaired.  I refused.  I have seen this issue mentioned many times in this and other forums so it is not specific to me.  AND, one tech that I spoke to for the original call WAS able to get it working properly.  Can anyone help? 

   I have purchased 6 dell desktops over the last 15 or so years.  This will be the last one.  The service is non-existent and the techs seemed content to just transfer me to someone else.  No one took ownership of my issue.  When I complained to a supervisor her offered me a discount on the maintenance agreement he was tryinng to seel me!!!  As far as I am concerned, these offshore support techs should be told that THEY REPRESENT DELL to the customer!!!  I am so frustrated by this experience that I would love to take this desktop machine and drop it on their doorstep!  I  guess I am going to have to go to a MAC if I ever want a machine that does more than Youtube videos and MS Office.
