Fix emul-setup-audio-volume.service using incorrect dependency

Fix emul-setup-audio-volume.service using incorrect dependency

The emul-setup-audio-volume.service runs before the udev event has been processed, so you can not access /dev/snd.

systemd-udevd.service only tells you that you are ready to process uevent.
You should use systemd-udev-settle.service to see if the actual uevent has been processed.
