Windows 10: Internal speakers not recognized as device, how do I get the internal speakers back?

I have a Dell Latitude 5430 running Windows 11. Audio output settings correctly showed both internal speakers and USB headphones. I had a temporary problem with headphones and mistakenly clicked "Don't Allow" button on the internal speakers in System>Sound>Properties. Now the internal speakers have disappeared from System>Sound>Properties and not recognized as a device. How do I get the internal speakers back?

can't detect internal speakers

I just upgraded to Windows 10. The computer doesn't recognize the internal speakers; audio troubleshoot wasn't helpful. Do I need to download a speaker driver or is that function internal to Win 10?

 

Switching off internal computer speakers

This is a subject that has been raised before but Microsoft seems to refuse to answer. As a result of a previous update to Windows 10, the internal computer speakers work as well as the external sound system. There is no apparent way to switch off the
internal speakers and just have the external sound system working. A previous contributor suggested that Microsoft had a solution to this bug but wouldn't elaborate. This seemed very childish.

I ask the question again: Could someone give a step by step process for switching off internal computer speakers AND leaving the external speakers working. I have tried every setting but nothing fixes the problem. Surely this isn't rocket science and
it would be easy for Microsoft to write a bug fix???

Lack of action just infuriates users unnecessarily.

 

no sound plays through internal speakers

I cannot get any sound to play through the internal speakers of my laptop. It did play previously. The speaker in the task bar has a red and white x and the trouble shooter says no speakers headphones plugged in. When I pull up the info on sound it lists
its location at HDMI port. Suggestions?
