I've running windows 10 for months, after installing it, I found my internal speakers don't work, had to plug and use external speaking. 

It doesn't read the sound card, use high definition devise.


I know some will laugh using this old machine but .....


No big deal  if there's no answer.


any ideas?

The Dell internal business speaker required use of the driver package supplied by Dell. They only officially supported up to Vista for that model, although it's suggested that the Vista driver would work in Windows 7, as a lot of Vista drivers did. Whether such a driver can be used in Windows 10 I'm not sure.


There's a discussion here:




with a link to a suggested package (R164900) encompassing Windows 7 if you wanted to try. Dell's support page for the Opti 755 has a listing for only one that says it's for XP.
