Following the instructions, still no audio. I tried also with a new OS as recommended by another user, nothing.
2 things to consider for future reference:
1. Windows won't detect any audio device as installed, like if there wasn't a Cirrus or Realtek in the mobo, it doesn't exist, no driver to install if there is no device to install the driver to.
2. I noted that when I configured it, I had no audio option in BIOS, but after a BIOS update it appeared. Before and after the update there was no audio.

Sadly I think that I'll give up since the client is a little anxious...

It won't turn on. When I press the power button i get an amber light on the charger led and nothing else....

I can boot using an external drive, so that fixes the USB issue, but still no audio and no m.2....

Can someone help me?
