AudioCommon: set volume _after_ starting stream

Fixes an error with the CoreAudio backend, which apparently doesn't
allow you to set the volume before starting the stream:

```
59:31:087 AudioCommon/CoreAudioSoundStream.cpp:97 E[Audio]: error setting volume
```

This shouldn't cause any problems with other backends, since the mixer
starts with silence anyways.
