The speakers are un-muted. They show properly in the volume mixer both in plasma GUI and alsamixer UI, when adjusting audio through the plasma GUI it shows the test tone is being played through the speakers but nothing is played.
When looking at the ASUS list on the Archwiki, your specific model is not listed but a few other zenbooks have problems with the sound. It could help to turn off fast boot in UEFI if you're dual booting and take a look at alsamixer:

I've found UEFI didn't work with certain distros before so I'm not surprised to hear it being a problem as usual. This was with my Acer laptop, ended up using legacy
Pretty sure my fast boot is off but I'll double check, also not dual booted.
Have already tried alsamixer and everything was unmuted and test tones still do not play. I assuming I'm SOL because it does seem to be an Asus issue but will double tap on the uefi fast boot, thanks
Ya already checked that, the gpu has a separate card that is for the HDMI port, and I have ensured its not set as default, and the card with the speakers is the default
