I haven't heard of it being fixed.  I still get it occasionally.  Then again, I'm using the original drivers for the sound card.

Also, the rep said that the screeching came from the SoundBlaster

 

so if i get the default "Integrated 7.1 Channel Audio " i wouldn't have to worry about it

 

is that true?

I have on-board. No screech...

I just bought a retail Soundblaster card for $100...Fatal1ty or what ever...screech no more

I 'm only getting the screech when i have headphones plugged in, no problems with the speakers

What Dell rep did you talk to? The sales people will lie to you to get a sale.
If you get the integrated sound, you will not get the screech. If you wish to upgrade later on, most people suggest buying a retail card instead of Dell's because of the driver issue with screeching.

 have an XPS 720, Dell X-FI xtremegamer sound card  , lots of screech , no fix i just called support and asked

Toronto: My recent solution was indeed to buy a new sound card. Of course, that was AFTER Dell was kind enough to issue a return and refund for the Dell card in both of my XPS 420s.

 

In my mind, that makes the Dell solution just fine.

Did everyone happen to notice the forum  "solution solved" was to buy a non Dell sound card..That Speaks Volumes about  the dell solution
