package gnome-power-manager tags 472637 + patch fixed-upstream thanks As suggested upstream, the patch from Subversion r2743 seems to fix this issue (and, as a bonus, g-p-m disconnects from pulseaudio when not actively making noise, which will hopefully cause the audio device to be released when pulseaudio is otherwise idle).
Please consider applying this patch in Debian if there isn't a release soon.
(Cc'ing Daf, who was also experiencing this bug)
Regards,
Simon
