Windows 10: Audio Stopped Working With New UPS

My APC UPS stopped working. I had a replacement CyberPower unit ready to go and installed it. Now there's no audio. Everything's hooked up right as far as I can tell, and another speaker won't play either, so it's not the speaker. When I pulled the CPU box away from the wall to get to the back, the green speaker wire plug came out of the box because it was too short, but it looks OK, and the connection hole in the computer seems OK. I have the (I guess) standard Realtek audio software. I've played with all the speaker/sound settings. Who knows if I got them back the way they're supposed to be, for example, line vs. Realtek Output Digital (Optical), and others. For example, see attachment.

When I turn on the speaker, it makes a scratchy sound. It did that at first. If I recall, I took that as a good sign and don't think I actually played anything to make sure. When I later tried to actually play something and turned on the speaker, it didn't make that sound. The speaker is getting power and should be getting input, but no sound. I don't know what optical output is, but it's just a standard speaker.

Audio services not responding - Audio randomly stopped working

Try the equivalent on your system of this (not all terms may precisely match your setup)

(from Guide: How to Fix Audio Not Working in Windows 10 : Windows10)

Note: as you may have found, a number of threads on this topic are unsolved.

You may wish to consider doing an in-place upgrade repair install if no solution is found.

Also consider the possibility of hardware failure. You could check the card is seated, cables secure.

 

audio stopped working, windows 10

upgraded to windows 10 by reservation few days ago... compatibility test result was fine... audio stopped working all of a sudden... tried upgrading the driver software in device manager
but in vain... also tried these methods suggested by Microsoft help community... but the audio is still not working, neither speakers nor headphones

Method 1:

I suggest you to run the Playing Audio troubleshooter and check if it helps.

• Type troubleshooting in the search bar.
• Select Troubleshooting.
• Select View all on the top left corner.
• Click on Playing Audio.
• Follow the on-screen instructions to run the troubleshooter.
• Check if issue persists.

Method 2:

If there no updated drivers available on the computer manufacturer’s website, then try installing it in compatibility mode. Compatibility mode runs the program using settings from a previous version of Windows. Follow these steps to install the drivers
in compatibility mode and check if that helps.

• Download the audio driver from the manufacturer’s website.

• Right-click on the driver setup file and click on ‘Properties’.
• Click on the ‘Compatibility’ tab and check the box ‘Run this program in compatibility mode for’ and select Windows 8/8.1 operating system from the drop down menu and proceed with the installation. Once this is done,
  restart the computer and check if the issue persists

 

After I installed the updates KB3176936, KB3176934, and KB3176495, the audio stopped working

I'm facing a problem after I installed the updates KB3176936, KB3176934, and KB3176495, the audio stopped working.

I contact Dell's support and together we tried to:

• Update the driver
• Reinstall the driver
• Uninstall the driver to use windows suggested drivers.
• Remove the drivers to use the microsoft drivers.
• Run sfc
• Run Dell Assist Tools
• Run Driver updates tools
• Uninstalled the Windows updates.

None fixed the problem.

During the RCA I restored my computer 3 times and the issue is not on the sound card, since when I restore the system it works.

I'd like to know what would be the next steps.

Is Microsft release a patch for the update that is breaking the audio?
