this is what i got from the ASUS support contact:
Hello Elad,
The Audio driver for 1903 needs update and test before upload to support site, and due to the resource, different model will have different priority, the time will be different than expected.
If you do not want to wait so long time, please provide us the information below, and we will key in system to provide a test driver of 1903 for the customer firstly.
1. The SN of the MB (Model: PRIME Z370-A).
2. A screenshot of the audio driver (Device Manager-> Propertites of the audio driver-> details tab-> Property: Hardware Ids).
3. The detailed version of your OS.
4. The main configuration, such as CPU/RAM/VGA card.
Kind Regards,

This was my reply:
Hi Idan,
Appreciate the effort in offering the below.
However, i could wait until you are done testing from your end for my model.
Do you have any roughly estimated ETA for when will the PRIME Z370-A motherboard get new drivers for Windows 10 1903 (specifically, the Audio driver)?
Meanwhile, i'm refraining from updating the Windows version to 1903 in order to avoid issues that are mentioned on the forum.
