No HDMI Audio on Pinebook Pro

To get HDMI working thru USB-C hub, I must install ‘linux-pinebookpro’ and video works fine. However, it will not send audio to the HDMI display. I tested the display from RPi4 on Ubuntu, and Windows8.1 connected to HDMI port without a USB hub and it does play audio. Is there something I can do on Manjaro PinebookPro to make audio pass through? Does the official Pine64 dock pass HDMI Audio from Manjaro?

As far as I know, HDMI audio over USB-C is not yet supported on the Pinebook Pro. :frowning:
