I think there is a bug in qTox: the result of deviceName.toUtf8() is 
temporary, and disappears by the time of the call to alcOpenDevice.

tmpDevName should be dissolved, and expression brought into 
alcOpenDevice argument:

alOutDev = 
alcOpenDevice(deviceName.isEmpty()?nullptr:deviceName.toUtf8().constData());


I will verify this.
