Speakers
Built-in speaker is supported on M1 and M2 MacBooks.
GPU
Do not use apps from Flatpak on Asahi Linux. They can not use system GPU drivers yet. Instead, build it from source.
Flatpak cannot use system GPU drivers, and there is no Flatpak runtime for the Asahi drivers yet. You cannot currently use GPU acceleration with Flatpak apps. - https://www.reddit.com/r/AsahiLinux/comments/105mbgo/comment/j3br7ju/
