No native support for apple silicon (macOS-arm64)

[danielkariv]

I tried to build the sample code from here :https://valvesoftware.github.io/steam-audio/doc/capi/getting-started.html but I can't link the given lib (photon) because it is built for x86_64 and not arm64. Adding support for arm64 on macOS should fix this issue.

OS version: MacOS Monterey 12.1 Chip: Apple M1 This is the error log I get after trying to compile it with g++(gcc).

We could really use an macOS arm build as well.

Hi all,

I left a post about this on the Steam Audio forum as well, but I thought I would follow up here with more detail in case it helps with resolving the issue more quickly. Here are the errors I am getting when I import the Steam Audio 4.1.3 package into Unity on an M1 Max MacBook Pro running macOS 13.2:

Thanks for your help with this!

Thanks @kisak-valve for directing me to this thread. Are there any updates on when Apple Silicon support might be provided for Steam Audio users?

We've just released v4.1.4, which adds support for Apple Silicon in macOS builds: https://github.com/ValveSoftware/steam-audio/releases/tag/v4.1.4.
