You can find more information about this problem in Qt at https://bugreports.qt.io/browse/QTBUG-36511 This was about QMediaPlayer, but the problem still exists for QAudioOutput and QSoundEffect.
A possible fix in Qt would be to check if the sink has flat volumes enabled and if it does, do software-based attenuation (in Qt). That way, QSoundEffect and QAudioOutput volumes would always be relative to the stream role's volume. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1485522 Title: Volume obtained is 100% in multimedia sink for sounds from app To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1485522/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
