[Qt-interest] Sound issues, CAudioOutput, Phonon

[Constantin Makshin]

QtMultimedia is at lower level than Phonon, but not too low (http://doc.qt.nokia.com/4.7/qtmultimedia.html).

Also, Qt developers said new features will go to QtMultimedia and they seem to have no plans to include Phonon in Qt 5+ (well, a lot of time may pass until Qt5 is released, but anyway).

And isn't Phonon::AudioOutput::setVolume[Decibel]() what you need?

P.S.:
Please send replies to the mailing list next time. Unless you want to start some private discussion, of course.
