Could be the same problem as I had on my XPS M1330. What is the audio and wireless configuration on your machine? I might be able to point you in one direction that's worked for me after hours of investigation, OS re-installs etc.

See my response on Page 1 of this thread. Basically you have to disable 802.11a Wireless Band. That cures it.

What did you do with your audio problem with the xps M1330?   I am running vista 32-bit.  I am getting not clear audio from the headphone jack.

Okay...I will try to disable that. 

 

FYI, there was only one page of the on this thread, didn't see any other posts.  But thanks for tip, I will try it out and let you know what that fixed it!

This is the thread that HeliBoy meant.
