No audio with USB-C HDMI adapter

[sunrez]

Hello,

Have my XPS13/9360/i7-8550u/16GB on Mojave 10.14.6 using kexts from here and almost everything is working, including built-in audio, touchpad, etc.

However, when using a USB-C to HDMI adapter video works but no options to route audio over HDMI show up. Using "QGeeM" brand adapter.

I did find a thread discussing this, not sure if it's needed : https://www.tonymacx86.com/threads/xps-9360-usb-c-to-hdmi-audio-still-not-working.216140/

I've definitely got audio over HDMI working before. But the adapter and TV brand matter.

Is there something I can do to debug? Is there an adapter brand you remember that works consistently? Do I need to try any steps outlined by bozman88 in that URL?
