Windows 10: What settings do I need to get my laptop's internal speaker to work?

When I play a DVD using my laptop's built-in DVD?CD player, the video plays, but there's no sound. How do I get the computer's internal speaker to work?

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?

 

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.

 

How do I mute my internal laptop speakers leaving external speakers on

Hello everyone, I'm a newbie. Windows 10. Incredibly I was innocently dusting my Del laptop keys when my computer sound (usually set on Pandora music) was muted, showing an 'x' over speaker icon on taskbar. Previously I could just click it to get it unmuted. This time it took about two hours of my time. Now I have sound coming out of both my external speakers and my internal speakers, when previously just plugging in my external speakers would mute my internal, or built-in, speakers. Is there any way I can mute my internal speakers without muting my external speakers without spending the rest of the day in troubleshooting, involving detailed examination of my motherboard and countless other steps?
Thanks for listening!
