My suggestion is not killing pulse, just redirect all sound to PA and let PA to send the audio to null sink or set snd-dummy as default sink so that wine can have exclusive excess
if those average end-user can use script using "amixer" which is equvialent to "amixer -D default" or "amixer -D pulse" to control volume via keyboard, he should also able to to rewrite the script to use "amixer -c0" to control volume
The lap-top built-in controls (button or volume knob) still use alsa api
it is rather a bug that PA cannot redirect all sound to the default sink

"The PulseAudio sound server has been rewritten to use timer-based audio scheduling instead of the traditional interrupt-driven approach."
The objective is lower the power consumption by reducing the number of wakeup for those laptop, netbook for a longer battery usable time without recharging.
"We minimize the overall number of interrupts, down to what the latency requirements of the connected clients allow us. i.e. we save power, don't show up in powertop anymore for normal music playback."
"We maximize drop-out safetyy, because we buffer up to 2s in the usual cases"
this is why it cannot support using those softsynth with those midi input device to play realtime music and playing interactive game
"We become much less dependant on what the sound hardware provides us with. We can configure wakeup times that are independant from the fragment settings that the hardware actually supports."
"We can provide almost any latency a client might request, dynamically without reconfiguration, without discontinuities in audio."
you will need PA to provide an option to tune the parameter from low power consumption mode to gamer mode for desktop to play those interactive game, otherwise the average end-users are still unable to tune the parameters in deamon.conf in order to play any application which require low latency
