Ok. Comment 4 says that media stuff is blocking on a D-Bus call. I have
tried it on krillin, mako and arale and could not observe this behavior.
We did have a screenshot related bug recently that would block for some
2 seconds when making a screenshot, however that one has been fixed and
for me it doesn't block/hang any more at all now.
If that still happens for you, and it always prints the log from comment
4, it probably implies something (I assume media-hub) being crashed
before and then playing the screenshot sound hangs, waiting on a sync
dbus reply from media hub.
@Pat, Jean-Baptiste: Can you try to find out more? Does this happen all
the time for you? Or only after some other steps? When in this state,
can you try invoking other actions that make a sound and see if those
hang? Perhaps creating a notification that plays the notification sound.
Adding back media-hub as comment 4 really points towards that.
