For external speakers not working in Windows 10, there are several reasons causing this problem. The speakers could be damaged, the sound could be muted, the audio driver could be faulty and so forth. If you encounter this problem, follow tips here to troubleshoot the problem and find the solution that works for you.
Firstly, check if the speakers have problem
When a device is not working, the first thing you should check is if the device itself is working properly. To check if the speakers have problem, try in on another and see if it works. If it works properly, there is no problem with the speakers. If not, you might need to replace it with a new one.
Secondly, make sure they are correctly plugged in to the computer (for desktop computers)
Many computers have three or more jacks that connect to a sound card or sound processor, including a microphone jack, line-in jack, and line-out jack.
Your speakers should be plugged in to the line-out jack. If you’re not sure which jack this is, try plugging your speakers or headphone in to each of the jacks to see if any of them produce sound.
Thirdly, make sure that your speaker volume isn’t muted or turned down too low.
If your speaker volume is muted or too slow, you can’t hear sound from the speakers. You can follow steps below to check and ensure the volume is set correctly.
1) On your keyboard, press Win+R (Windows logo key and R key) at the same time to invoke the run box.
2) Type control panel and click OK. This is to open Control Panel window.
3) In Control Panel, view by Category, click Hardware and Sound.
4) Under Sound, click Adjust system volume.
5) If the sound is muted, you will a line cross built icon the button (see below screenshot). In that case, click the speaker icon to unmute it. If the sound is already unmuted, move to next step.
6) Move the slider up to increase the volume.
If the problem still cannot be resolved, try solutions below. Sound setting problems or driver problems may also cause this problem.
