Audio Device Volume
I need raw audio input and output with system volume control.
QAudioOutput and QAudioInput do not seem to support volume control so I thouhgt of using Phonon but Phonon does not seem to support audio inputs.
How could I access the system volume (Window System).
There is a discussion going on about a Qt audio mixer API:
You can vote this feature request up. For the time being I do not know of a Qt way to control the mixer.
