In /usr/lib/pm-utils/sleep.d/01PulseAudio, I noticed that the output of
the function get_pulse_users() was returning my user ID as a number, not
as the name of the user. Further down, that's used in the "sudh -H -u"
commands, but sudo will only take a number UID if you enclose it in
quotes and add a number sign:
sudo -H -u $i pactl suspend-sink 1 &> /dev/null
becomes
sudo -H -u "#$i" pactl suspend-sink 1 &> /dev/null
Making this change to all the instances of that made suspend start
working for me every time.
Try running the command:
ps aux | awk '/\/usr\/bin\/pulseaudio --start/ {print $1}'
It's the same as is used in that get_pulse_users() function. If it
returns a number, the above fix is needed. At least, it worked for me.
