HDX 16t Audio Problems

Ever since I have had my HDX 16t I have been plagued with problems with the audio acting weird in different ways.

For example, like several other users have probably experienced is the 50% CPU usage from the STacSV.exe process, which is related to the headphone jacks.

I have gone through so many different driver version of the audio drivers trying to fix the problem. I have also tried the generic drivers that come with Windows, however none of those drivers works flawlessly. I have tried reinstalling Windows many, many time but that makes no difference.

I have even though through some massive threads such as this one http://h30434.www3.hp.com/psg/board/message?board.id=Sound&thread.id=609&view=by_date_ascending&page=1

However, I still have not found a solution to my problem. I tried sending it into to HP for repair but they weren't able to do anything for me because they say there are no problems, thus there is nothing they can do.

I would like to get this problem fixed and have HP repair center people find the problem and recognized it. Does anyone have any suggestions for a good way to replicate the 50% CPU utilization because of the rogue STacSV.exe process above?

 

Have you guys experienced this problem too and not just found a solution?

I would like to hear your guys feedback

 

i have the same problem
using process explorer i end it..
then all comes to normal...

 

Do you guys know of a good way to replicate the 50% CPU usage problem? I am trying to figure out a way to make good instructions so that tech support people at the repair center can see the same problem too.
