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".
