I have set a qemu version of MacOS in my Ubuntu 22.04. Everything is apparently ok (even if it is not always very fast), but sound is working quite bad. I can hear sound, but it is often flickering and when I try to open a youtube video in a browser the system starts to slow down.
I tried to check around some solutions (for instance using AC97 device or specifying the setting for PulseAudio [https://stackoverflow.com/questions/64560389/setting-up-pulseaudio-in-qemu]), but I am note sure if this could help.
My basic.sh has these lines
