Try updating the driver and check if it helps: a. Designcad pro 2000 free download. Click on 'Start' and type 'Device Manager' in the start search box and press enter. Click on 'Sound, video, and game controllers' to expand the list. Right-click on IDT High definition audio codec and 'Update driver'.

I updated From WIndows 7 to Windows 10 in March; on board sound system worked fine at that point. Since one of the updates this summer (July 12, I think, though it could have been later), the internal speakers do not work; the computer does not recognize the presence of internal speakers (only external speakers and microphone). I have tried using Device Manager to update drivers: sound and audio controllers--HD Audio device--runs the update and says my drivers are up to date (but only registers the external speakers).

I have tried searching the HP site for the driver compatible with my setup--no luck. Can you either help me get to the driver link or suggest another solution? Is it possible to recover and use (e.g.) the driver that I had for Windows 7? Or another earlier operating system?
