Alyssa Ross f310f2c121 vhost-device-sound: test dbus-daemon from PATH 
On my NixOS system, dbus-daemon is not at /usr/bin/dbus-daemon, but on
systems where it is, it should also be in PATH.

Synopsis

   vhost-device-sound --socket <SOCKET> --backend <BACKEND>

Description

   A virtio-sound device using the vhost-user protocol.

Options

     --socket <SOCKET>
            vhost-user Unix domain socket path

     --backend <BACKEND>
            audio backend to be used [possible values: null, pipewire, alsa, gstreamer]

     -h, --help
            Print help

     -V, --version
            Print version

Examples

Launch the backend on the host machine:

host# vhost-device-sound --socket /tmp/snd.sock --backend null

With QEMU, you can add a virtio device that uses the backend's socket with the following flags:

-chardev socket,id=vsnd,path=/tmp/snd.sock \
-device vhost-user-snd-pci,chardev=vsnd,id=snd
