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).
