    Description

      When executing the start () method of QAudioOutput that is a member of an object that has been moved to another thread, the warning QObject :: startTimer: Timers cannot be started from another thread is displayed.

      Analyzing the QAudioOutput's constructor code I noticed that QAudioDeviceFactory does not attach the parent, as a result of moving to another thread the only QAudioOutput member is not moved, causing the warning.

      I attached a simple project to illustrate.
