Start VOX with BT headphones on and working. Listen to music.
Go to apple audio output menu from top task bar on mac desktop. Change to another output such as the display’s builtin speaker.
VOX audio is no longer audible.
Checked output volume. Tried switching back to BT. App UI shows the song playing. Time ticking up. App’s UI also showed the audio change event as a message.
Have to kill the app and restart to get audio to work on new output.
