dell xps 1645 - speakers problem

This question is not answered

Hi

Last week my speakers were working.

My headphone outputs, both are working

My external soundcard  output is working

I made the diagnostic test, and the speakers of the laptop sound perfectly 

They are not mute. 

I reinstalled the drivers.

I restored to a previous date when they were working....

Somebody can help me? 

Thanks in advance

  • You probably have a failed sense pin. The way to diagnose that problem is explained in the Headphone Jack FAQ. Start at reading at the 2nd section "Newer Laptops with HD Audio on the System Board".
