i have a Dell Optiplex 755 that i have done a clean install of Windows 7 on.
all is working OK, but i am having an audio problem.

I installed the Vista audio drivers for this model from the Dell website and the audio appears to be OK (windows detects it and gives volume control).
however i was expecting to hear sound from the internal speaker, but i get no sound at all.

should i be able to get sound from the internal speaker?
