No audio output on MacOS Big Sur - Is there a known solution?

Operating system

Arch Linux (Linux 6.6.57-1-lts)

Description

I would like to know if it's possible to use audio in this container. I currently have a QEMU/KVM VM running MacOS Catalina where audio works perfectly - I can select Line-out(green n/a) in audio devices, and both audio output and microphone work within the VM.

However, when trying more recent systems like Ventura or Big Sur, I encounter issues with audio. I first installed Big Sur using this repository (thank you for your work, by the way) and everything works perfectly except for audio - no devices appear in the audio selection.

To troubleshoot this, I tried several approaches:

1. Installing Big Sur directly through QEMU - same audio issue persisted
2. Updating my working Catalina VM (where audio works) to Big Sur - after the update, audio stopped working and no input/output devices appeared in the selection
3. Tried various parameters and configurations, but none resolved the audio issue

I would like to enable audio functionality, but I suspect this might not be possible yet with newer MacOS versions. Is there any known solution or is this a current limitation of the setup?

Environment tested:

• Direct QEMU/KVM installation
• Docker container installation
• Catalina upgrade to Big Sur
