Audio stopped working after upgrading win11 to 22H2

Hi Rocassa45

Sorry to hear you are still having issues. I don't use Audacity but used to use Ableton Live and used to have lots of issues whenever I had any other sound drivers installed, except the Realtek so I understand how frustrating this is. I think you're right holding off for now. I looked for a solution to your monitor problem but all I could find were that Microsoft had recognised there was an issue and was working on a fix. (Which usually means very little) I updated this morning and suddenly had no sound which was also causing errors using my media players. Fortunately, I remembered when I updated to Windows 11 I had exactly the same problem so I eventually came to try this and it worked. I don't seem to be having any more problems (fingers crossed). Sorry I couldn't be more help. Hope you get it sorted :)

i thought i was the only one.

Alienware X15 R1, upgraded to 11 22h2 yesteday and now my audio is weird out.

For context:

i log in via windows hello and audio is working as default windows login sound plays. Then i tried to test the audio by going to sound settings and then volume testing 'ping' sound works.

so i left the computer idle, not playing any audio for a few seconds.

after that, tried to test the audio again and now the 'ping' volume test sound do not plays. Launching a browser and browsing youtube and clicking a video, no audio was played.

On the volume mixer and sound settings, audio is NOT muted and volume bar shows that sound is playing (because you can see the bar is increasing and decreasing), yet there's no audio out from the speaker at all.

The only workaround i found is to go to sound setting, enable Mono audio, and audio plays again out from the speaker. Disable Mono audio and the audio continues to play in stereo as well.

And if i continues to let the youtube video plays, the audio will play no problem and continues to play. until i stopped the audio activity, leaved it idle with no audio playing, then continues to play the audio and it's back to square one again with the need to apply the same workaround.

Audio playback device is realtek and i've updated to the latest version as provided by Dell.

Any advise?

Quick comment: "Was this reply helpful" is confusing. Like others, I respect and appreciate any attempt to help. I rate the Help according to my personal (problem). Thus, few Stars does not mean impolite dismissal of the suggestion.

I've just upgraded (with a Restore Point of course; I do not trust MS at all right now!) to 22H2 Build 2262.521. And sure enough, as so often, my Audacity (Recording settings) which were working are screwed. It took half an hour of trying System (Sounds) and Sounds/Control Panel permutations to get it working again.

Does anyone else experience this frequently after Updating? I repeat, a year or so old machine with a Gen 11 CPU.

I was experiencing this same issue. I resolved it by going to my motherboard manufacturer website and searching for the audio driver they provide. It was a newer version than the one I had currently installed, and installing this latest version allowed my sound to start working again. Unfortunately, this driver update was not available via Windows Update.

Your mileage may vary, but it does seem like the 22H2 update is not grabbing the latest Realtek audio driver.

After W11 22H2 update I also had sound problems with USB external Audio Interface (UMC22) .

There was no problem with bluetooth and headphone jack inputs. After checking the speakers, audio interface and computer cables and restarting the devices, the problem persisted.

I had sound problem only with UMC22 USB Audio CODEC.

I also reinstalled ASIO4ALL 2.15, 2.14 and 2.13 versions but that didn't work either.

When I uninstalled the USB Audio CODEC driver from the device manager and restarted the computer, I could only get an extremely low volume with the headphones.

Finally, I uninstalled Intel Smart Sound Technology for USB Audio and USB Audio CODEC drivers from device manager and all ASIO4ALL installation and restarted my computer.

After the computer was turned on, I just installed the latest version of ASIO4ALL 1.5 and it started working as before.
