Windows 10: Audio Devices via DP/HDMI "disappearing" after 2004 update

After updating to 2004, either my monitor or tv would disappear from the audio device list when:

(monitor is on, I turn on tv, and turning tv back off.)

It would only show either the monitor or tv on the audio devices list. Unplugging and plugging hdmi/dp cable would not work since it would only show the last connected device's audio.

Downgrading GPU and GPU audio driver did not work, "workarounds" are either to reboot or disable and re-enabling Nvidia audio driver

HDMI audio driver for ASUS X551M laptop?

This is from Intel regarding hdmi:

• Install the latest Intel® Graphics Driver, this also installs the latest audio codecs for HDMI.
• After driver installation, connect to the HDMI TV or digital display, using a HDMI cable.
• Select HDMI audio as your default playback device. Click Start>Control Panel>Hardware and Sound.
• Click Sound. The Playback tab lists the audio playback devices for your computer.
• Right-click on the device for HDMI audio, and select Set as Default Device.

No HDMI audio output in Device Manager

The above step did not work for me. The windows audio troubleshooting tool did not fix anything.

Hi, I have the same issue. I have a Toshiba P75-A7200 laptop, I think a recent update to windows 10 removed it, because it wont even show in my available playback device list. My intel drivers are installed
and my audio drivers as well, but HDMI audio wont show up. I have tried this on other TVs with different HDMI cables with no luck.
