Bug: Sound FX come out of speaker when BT connected

[mpogue2]

SquareDesk status line says that "Thunder Flash" (Bose BT headphones) are connected, and when I click Play, music comes out of the headphones. BUT, when I hit Cmd-2 to get a sound effect, it comes out of the MacBook Air's speaker, instead of the BT headset.

I don't know whether this problem occurs when connected to the mixer via the headphone jack.

Same as #1093.

Here's what's happening:

• This bug only happens if SquareDesk is started and THEN the system sound output device changes.
• SoundFX are played via QMediaPlayer, which doesn't seem to get the memo that the output device has changed.
• If the Settings control panel is used to change the output device BEFORE SquareDesk is started, then the music output and the soundFX output both go to the correct output device. If the Settings control panel is used to change the output device AFTER SquareDesk is started, then music correctly goes to the updated output device, but QMediaPlayer output goes to the old output device.

The fix is to always tell the soundEffect QMediaPlayer to setAudioOutput to the current default-constructed QAudioOutput, which correctly reflects the CURRENT sound output device setting.
