Via SPDIF hearable sound starts late, e. g. in the Test Sound dialog I maximally can hear "Left" when the voice should say "Front Left".
When I have
pavucontrol open (in the background) whilst clicking on the Test Sound it starts immediately.
Generally, starting any audio/media file, the beginning is not output/hearable. Connecting either optical or coaxial. This only seems to affect Ubuntu 12.10, wasn't the case in 12.04, doesn't seem to be the case in 13.04!
From ubuntuusers.de a bit of help -- playing a non hearable sinus to keep spdif alive:
apt-get install sox play -n -c2 synth sin gain -100 # -c2 for two channels

Can I upgrade from pulseaudio 2.1 somehow?
Live Ubuntu 13.04 output pasted to http://paste.ubuntu.com/5630475/ -- actually here only the very first invocation of sound (or after some long user pause?) starts delayed, ie after "... Left", "Front Right" is heard whereas in 12.10 it's always "... Left", " ... Right".
