Fixed bug #728
I am using a headset on my monitor as primary sound output device. From time to
time it happens that I switch off my monitor when I leave my computer and
switch it on when I come back.
When doing so while wesnoth is running I get no sound back when I switch on my
monitor. There is probably good reason for that. Therefore I wanted to exit and
restart wesnoth. Unfortunately, wesnoth always hangs in this situation. It
looks like wesnoth can not be exited when the primary sound device vanished.
I created a backtrace of this situation (please see attachment).
