HDMI audio share on Poly x50

[StCloudState]

New issue for rooms in use many years. 

Laptop connected to HDMI, Poly x50 HDMI in, shares video but not audio. Connecting same laptop to PC monitor with speakers plays audio. There used to be a setting for hdmi content sharing, audio enable, which seems to be what is happening. But I cannot find this setting anywhere. 

Need, A/V shared over HDMI to Poly x50 Zoom Room. Just updated Zoom and Poly software...

@StCloudState sorry for the late reply.

When sharing audio via HDMI, the laptop must be configured to use the HDMI connection as its speaker output device.  For example, on a Windows laptop, the user must click the audio icon in the system tray, then click the output device options, then choose the speaker device that represents HDMI (this is labeled "Digital Audio (HDMI) (HD Audio Driver for Display Audio)" on my laptop.  On Windows 11 (possibly also Windows 10) you can open this menu with [windows-key] + CTRL + v.  On a macOS laptop, you would go to System Settings > Sound, select Output, and select "HDMI Audio".  If the sound icon is in the menu bar, you could select it there, instead.
