Windows 10 - no sound on internal speakers

HP dc7900SFF - Intel Core 2 Du
Microsoft Windows 10 (64-bit)
Hi

I have upgraded from Windows 7 to 10 and now have no sound on internal
speakers. I have tried updating the sound driver which is up to date but still
no sound.
The external speaker is fine.
Any ideas please

Hi:

 

I used the W7 Soundmax audio driver on the dc7900 support page and it worked great.

 

You have to install it, restart the PC, go to the black soundmax control panel icon and check multi streaming.

 

Restart the PC, go to the control panel, hardware and sound>sound>manage audio devices and select the speakers as the default.
