PineTab 2 HDMI sound output not available

[k8ieone]

Device info (please complete the following information)

• Device: PineTab2
• Kernel Version : 6.12.3-danctnix1-1-pinetab2
• UI: Phosh

Describe the bug
Connecting the tablet to a TV or a screen with speakers using the micro HDMI port doesn't switch the sound to HDMI. Looking through pavucontrol there doesn't seem to be any way to make it work. No different profile or separate device.

I also tried to turn the device off, plug in the HDMI port and only turn it on with the screen connected. Doesn't seem to change anything.

To Reproduce
Steps to reproduce the behavior:

1. (optional - power up the device with HDMI connected)
2. Check sound devices in settings

Expected behavior
Either a separate audio device or an alternative sound profile should be available when an external HDMI screen is connected.
