Windows 7: Having problems with onboard audio with a Dell Optiplex 745 and W7

Having problems with onboard audio with a Dell Optiplex 745 and W7

I've been refurbishing some Dell Optiplexes and have run into a problem.

The Optiplex 755 runs Windows 7 perfectly, with good volume for the onboard audio.

With the 745s though, the audio is extremely low and faint. I've tried running the audio drivers in compatibility mode and as administrator, but nothing seems to work.

Does anyone know of a way to get the existing drivers to provide louder volume, or a different driver that may work?

It looks like the integrated audio is 'ADI 1983 High Definition Audio'

Thanks for any information.

Windows 10 64 bit

I do a lot of user support on the Dell forum. We have found that Dell supplied sound drivers need to be used with most Dell's as non-Dell sound drivers either do not work or do not work correctly. Vista/Win 7 handles some functions differently than XP and because of this they usually don't work or work right.

HERE is the Vista 32/64 bit sound driver and it will work for Win 7. Give it a try, if you have not tried it.

If this doesn't fix it, repost the problem on the Dell Desktop hardware section for more help.

Thanks for your reply.

I'm getting some more 745s next week and I'll let you know if this works.
