First thing is to make sure you have a current PA as there has been a lot 
of work on it in the past few years. Things that didn't work or not right 
in 2012 have been fixed and work now. [edit, this does not seem to be 
fixed lp:#1232295 is not closed] I don't personally know about 
suspend because I don't happen to need/use it. Once PA gets restarted 
though, I don't think there is much you can do about chromium/firefox 
although just reloading the page should bring it back because the pulse 
port is not opened by gstream until/unless the web page needs it. It 
should be the same with many other desktop apps (which is why PA-jack is 
so useful). Many of them shut the port just with a pause and certainly 
with a stop/play (but that would loose the place you were if part way 
through a movie). This page:
https://wiki.archlinux.org/index.php/PulseAudio#No_sound_after_resume_from_suspend
Suggests that pulseaudio -k is not the best thing to do and that using 
pasuspender will not break running applications like the browser. The 
script on the same page will only work if you have systemd running the 
system... so not debian or derivatives (just yet).

It sounds like jackdbus has made it through the suspend ok anyway.
