Windows 10: Sound doesn’t work after recent update

I have no idea if this is the right place to ask this but after the recent windows 10 update my speakers no longer work. I went into my sound devices and the device that I use says that the driver is unavailable. I’m not sure what that means or what I have to do fix the issue.

Windows sound not playing after recent Win10 Update

Hi all,

Symptom:
Since last windows update, windows doesn't play the windows sounds: Startup, UAC sound, exclamation, warning, notifications, etc.

Note: Other sounds, like games, videos, calls are working well.

I use SoundBlaster Z series sound card. Their recent driver update release notes lists that the driver is fixing this issue.

Actions taken:
Removed the driver completely
rebooted
Reinstalled the driver

Results:
After initial boot and subsequent restarts, the windows sounds play well.
After a computer shutdown and startup - the above symptom is introduced again, i.e., windows sounds don't play anymore.

I've repeated the steps above and ended up with the same problem.

Can anyone please assist?


Win10 Pro
Version 1909
OS Build 18363.657

Thanks.

 

sound devices not working after recent Windows Update

I have a Windows 10 computer (an Intel NUC) with built-in sound (Realtek) and an external USB-driver D/A convertor (essentially a USB sound card).

Some time after an update (although I'm not sure these incidents are related), my sound control panel now shows "no output devices found." So both the Realtek and my D/A convertor have disappeared.

(Note: the D/A convertor uses an Audio Class 2 driver provided by XMOS.)

The latest XMOS driver doesn't fix the problems with the D/A convertor. I haven't tried changing the Realtek Driver. I found a blog post that suggested a recent update pushed the wrong version of an Intel SST driver.

I have version 9.21.0.4260 of the SST driver, which according to the blog post is NOT the problematic version.

Troubleshooting my audio results in the message "plug in a sound device" which I presume means plug something into the headphone jack on the NUC. I tried this, and no change, neither sound device was present.

Any suggestions at this point?

 

Hdmi sound not working

Hi Peter,

One possible reason why the HDMI sound does not work is due to the conflicts with the playback settings. For us to help you make the HDMI sound to work, we suggest that you answer the following questions for further research:

• Have you made any recent changes to your computer?
• What is the current build and version of your Windows 10?
• Have you tried to download and install the most updated sound and display driver of your computer?

Meanwhile, we suggest that you perform the steps on this
article as our initial troubleshooting and see if there will be any changes on the HDMI sound.

We'll be waiting for your response.
