Hello to everyone.

Below you see the working parameters to boot up Android Cuttlefish on top
of Ubuntu 24.04 using qemu-system-aarch64 :

What's the problem ? this :


2024-10-04T14:16:02.093367Z qemu-system-aarch64: -device AC97: no default
audio driver available
Detected unexpected exit of monitored subprocess
/usr/bin/qemu-system-aarch64


Do you know what packages that I should install on Ubuntu 24.04 to enable
the device AC97 ? thanks.
