Windows 10: Sound/internal speakers suddenly not working

Sound will not work. Windows 10, have performed sound system scan for repair and reboot as instructed. Nothing. Looking under 'manage sound devices' no device listed - so I can't "enable". Sound has worked before. How do I get the system to recognize the built in speakers on my laptop?

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?

 

Windows 10 Internal Speakers not working suddenly

I installed Windows 10 weeks ago, and everything was running fine, but last week the sound suddenly stopped coming out of the internal speakers. It worked fine through the headphones, but it was
just the internal speakers that weren't working. I sent it in for repairs since I had my laptop was on warranty, and a they had to do a complete reset on my laptop in order to fix it.

My question is, was windows 10 what caused it? I'm doubtful that it was, since my speakers were absolutely fine for weeks and weeks, but since they work after a wipe it seems possible that windows 10 caused it. Any thoughts?

 

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.
