Mumble on Windows does not warn when no audio device is available

[mkrautz]

Perdouille reports on IRC that Mumble on Windows doesn't give any hints when audio devices are not available:

20:57 < Perdouille> Hello !
20:58 < Perdouille> Got a little question : The "This is a example of Speech, an audio compression codec specifically tuned for the reproduction of human speak" thing (I don't remember the exact sentence ^^) isn't in Mumble anymore ?
20:58 < Perdouille> (I'm using the lastest 1.3.0 snapshot)
20:59 < Perdouille> And it's saying that there's something showing my position and stuff but there's nothing (I don't know how it's translated, here's a screen : http://puu.sh/mPIuU/cb23f180ce.png )
21:01 < Perdouille_> I crashed :/
21:05 < Perdouille_> Okay fixed, it was a bug on my end (Mumble couldn't access the audio device because it was already used by another software)
21:12 <@mkrautz> Perdouille_: for both bugs?
21:14 < Perdouille> Damn I keep crashing
21:14 < Perdouille> I said : Yes both bugs got fixed : I installed VoiceMeeter to make fake audio canals, and it fucked up a bit with Mumble because it couldn't access my real audio device
21:15 <@mkrautz> ok, thanks for the confirmation!
21:15 < Perdouille> But it didn't say anything, that would be nice to have an error message if there's a problem like that (I remember having an error message when I had Pulseaudio problems when I was using Mumble under Linux, but nothing under Windows)
21:16 <@mkrautz> yes, I agree.

Guidance from the software vendor's forum suggests it could be related to their software version:

Since that wasn't supplied in the issue the best we can probably do is provide the above URL for historic purposes.

We should still warn the user in case no audio devices are found, otherwise the audio wizard appears not to be working.

The issue seemed to be that it was "in use" as opposed to not present. Testing for not present we should just be able to install it on a VM with no audio devices. Do we not have a part of the Setup Wizard that announces this state?

We don't, the device list is simply empty.
