Hi. Very strange. I have more simple CPU - AMD Athlon 3000G with int Radeon Vega 3 and mobo ASUS PRIME A320M-K.
When i boot MacOS 13 Ventura all audio out works - and line out on backside panel and if i connect old TV Samsung over hdmi cable. Check settings sound - may be on your system Line Out as default?
When i think this kexst project orient on graphics, no sound.

It is actually a known issue and it has no known cause or solution. The problem only appears on a very small amount of devices.

Ahem. Let's see if you can ignore the developer (me) now.

We have already tried numerous things, including different AppleALC layouts, cables, changing volume, removing AppleALC. Nothing we tried works and, as mentioned previously, the cause is not known.
