Windows 10: No audio output devices installed but devices show up on device manager

Hi, my PC always has a red cross on the sound icon at the taskbar whenever I turn it on. I take a look at the sound settings on the control panel and there are no audio devices listed at the playback menu. I look at the device manager and there are literally 5 audio devices and 4 audio controllers that work. There isn't a single error message on these devices, but Windows doesn't seem to pick any of them. Most of the time this issue doesn't get fixed unless I toggle the mono audio option in the settings on and off I don't have a clue about how the mono audio option is connected with audio out

:)

 

No audio output device is installed

A screenshot of the Device Manager, Sounds section is still needed. Can't really offer a suggestion until I see what is showing there now.

e.g this is mine It shows AMD which the audio for HDMI, Realtek and Tranzport which is a wireless controller for my recording studio program.

 

No audio output device

Hello!
I have a common problem: my Windows 10 has No Audio Output Device.
System configuration:

• Lenovo Legion Y520-15IKBN (laptop)
• Windows 10 Pro, version 1909, build 18363.535;
• Current updates;

Device manager shows these audio devices:

• High Definition Audio Device (driver version 10.0.18362.356)
• Intel Display Audio (10.27.0.6)
• ASUS Xonar U3 (10.0.8.2164)

i.e. the problem persists even with an external (USB) audio device, recognized by the system.

I performed a sanity check on this issue. Sound works when I boot into Ubuntu live. Therefore, it is not a hardware problem, and is indeed a Windows problem.

Solutions that have not worked so far:

1. Audio troubleshooter (issues found: check audio device, nothing else)
2. Rolling back drivers
3. Uninstalling audio devices
4. Uninstalling any audio-related devices, incl. the likes of bluetooth speakers
5. Updating audio drivers (from both built-in drivers and from manufacturer's site)
6. Installing a generic audio device (installing a generic USB audio device does not succeed, and installing a generic Realtek device resulted in a BSOD)

Do you have any ideas for fixing this?

 

audio output device

My surface pro seven suddenly does not have sound. It says there is no audio output driver. I talked to someone at microsoft and they had me uninstall and reinstall updates. I cannot reinstall an audio driver because the device manager list of devices does
not even show sound as an option anymore. The rep I talked to finally said he had no more suggestions.

I am not sure how to fix this or why it happened.
