That seems like the wrong approach. sound.target does not have any
dependencies on /tmp.
If anything, it's pulseaudio which should ensure that /tmp is mounted.

I am confused though: Are you suggesteting that pulseaudio is started by
sound.target?
pulseaudio.service is supposed to be a systemd user service so this
doesn't really make sense.

Is it possible that pulseaudio is started via other means which are not
under systemd's control?
