event sounds are played only through the left speaker

Now that Karmic uses the PA backend of libcanberra I have noticed that the event sounds play only through the left speaker.

It should play the sound dependent of the button position on the screen.

If the position of the button is more left on the screen it should play the event sound through the left speaker and if the button is more on the right side of the screen it should play the event sound through the right speaker.

To make this easy visible to the eyes, take a look at pavucontrol, there you can see to which speaker the sounds are played.

I have seen someone else noticed such a behavior.

The sound files affected are all mono (in /usr/share/sounds/ubuntu/stereo/ bell.ogg, dialog-error.ogg etc), the stereo ones work fine. The mono files are not properly upscaled to more than one channel.

the problem is fixed in libcanberra 0.16, so we only need a new package.

Contains a new API call "ca_context_playing()" which can be used to
find out whether a sound is still playing.
