I have a Compaq CQ58, with Windows 8.1 installed.
Product number: D1L62EA#UUW.
I am having problems with the sound disappearing.
It started a few days ago and after looking at some of the forum suggestions I managed by good luck to get the sound back, though I am not sure exactly what I did to succeed,but it seems that as soon as I turn the PC off then I have no sound again.
The system is telling me that the speakers are working and I can see when I open the Volume mixer that there is sound on the unit.
Best regards
