Hi there, I recently upgraded my dell 9100 pc from windows XP (32bit) to windows 7 (64bit) but now my speakers don't produce any sound. I had to have the soundcard replaced a few months ago because the original one stopped working and it's listed as "High Definition Audio Device" in the device manager area. I've updated the drivers to ensure they're up to date but it seems that the computer doesn't detect the speakers. They're just standard dell ones, I uploaded a picture to imageshack of one of them: http://img80.imageshack.us/i/1001066p.jpg/
the manual for the dell 9100 is here: http://support.dell.com/support/edocs/systems/dim9100/e... although i've slightly upgraded this one so it has 4 G.B. of R.A.M. and a Radeon H.D.4760 graphics card and a 450W. power supply. I'm not sure what would be causing them not to work, my tritton A.X.720 headset so i've just been using that for sound recently.
Dell has not posted any W7x64 drivers for your machine. Since W7 did not have the driver, we'll need to know the soundcard manufacturer and model number. If you can tell us that, we can point you to the W7x64 drivers, or you could google the make and model yourself.
I can't access the soundcard because it has a big L shaped block thing in the way and it's below the graphics card so I can't see it although, I've managed to get the speakers working in onboard sound slot for the motherboard so I'll just use that for now. I was intending on replacing this computer when the AVG license expires (next June) since I've had it for 5-6 years now and I can't upgrade it any further. It should be ok for the next few months for my mum to use up until I replace it. Won't be buying a dell computer again though, the computers at http://www.pcspecialist.co.uk/pcs/ are much better value and let you choose exactly what goes in. Thanks for the response anyway though
