Speakers thru a factory-installed sound card on a Dell Optiplex GX520 do not work with Windows 10. USB headphones are OK - do they have separate drivers or none at all?
The system tells me the most up to date driver is installed for the audio. The test in the volume mixer does not play.
What's my next step? I don't have another set of speakers to try. I have another original soundcard and driver so could install that, alternatively I could find a new card that should work with Windows 10. I just need the basics, a decent music sound, no high fidelity gaming effects etc!
