Audio Device Volume

 

Hi,

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).

Greetings,

There is a discussion going on about a Qt audio mixer API:
http://bugreports.qt.nokia.com/browse/QTMOBILITY-1134

You can vote this feature request up. For the time being I do not know of a Qt way to control the mixer.

Hi,

I have actually already implemented most of the Windowsmixer code now. I’ll provide it to the developers, maybe it can contribute to the further development.

If anyone needs it directly, please contact me.

Best regards,

Eddy
