I believe that libcanberra always ensures that event sounds are played
on the default sink. Not sure of the inner workings there nor of whether
it should be a stream-restore job (it's capable of routing e.g. all
event sounds to a given sink, overriding (IIRC) the per-application
device rules.

Incidentally, when playing with pidgin, are you sure paplay is the right
thing to use... in the absence of direct libcanberra support, could you
not use "canberra-gtk-play -i message-new-instant" or similar to play
the relevant sound from the FDO sound theme naming spec[1] when the
appropriate action occurs. I'd imagine writing a libcanberra plugin for
purple/pidgin wouldn't be very hard at all... basically just bridging
code.... (although this is without the benefit of looking at either set
of APIs in any great depth :p)


Incidentally Lennart, can you sort out the following:

http://0pointer.de/public/sound-theme-spec.html :
Version says 0.2 at the top, change summary mentions 0.5.

http://www.freedesktop.org/wiki/Specifications/sound-theme-spec :
Links to the above link as "version 0.3" (not 0.2 or 0.5 as expected!)


This is very confusing - can all links and versions linked from the
official places please be made to be the most recent versions?
