Add the `,audiodev=` property to audio devices when machine version is 4.2 or higher.
With Qemu 4.2 a new `audiodev` property was introduced [0] to explicitly specify the backend to be used for the audio device. This is accompanied with a warning that the fallback to the default audio backend is deprecated. [0] https://wiki.qemu.org/ChangeLog/4.2#Audio Signed-off-by: Aaron Lauterer <a.laute...@proxmox.com> --- tested this with all 3 audio devices available in a local VM and one live migration from a qemu 4.1 node to a 4.2 node with the default ich9-intel-hda dev.
