Right now the RealTek ACL294 sound device is not fully supported in ALSA on the Asus GX502GW. This is because it's a new configuration so it hasn't been patched into ALSA yet.
This is impacting Arch and Debian distros, and the newest kernel that I have tested (5.4.0-37) is the same.

It may be worth making a ticket on ALSA to support this OOTB.
