I did some testing on KXStudio, which has a complex pulse, jack, and
alsa setup. However, I turned off and reconfigured things to simplify
and try out different scenarios. For me, the ALSA output (Kino
preferences audio device = 'default' or other pcm) seems to always
misbehave now. It will play ~600 frames very quickly and then start
playing normal. It makes no difference if pulseaudio is running or not
or if I use pasuspender. Jack was not running, but when it is Kino
will deadlock.

When I set Kino preferences audio device = '/dev/dsp' then it works
whether pulseaudio is running or not. In this mode, it is using the
ALSA OSS emulation modules. 'padsp kino' does not succeed to route the
audio through pulseaudio. It might be that some hardware/drivers
permit multiple apps to open the audio device and others not. If
multiple opens is not supported, then this will probably not work
without stopping pulseaudio ('pulseaudio --kill', 'pulseaudio --start'
to restart) or perhaps using pasuspender ('pasuspender -- kino').
