Magic Music Visuals

Maybe silly to ask, but when hit the play button on Audio/MIDI panel, audio file does not play at all.
Any help, please.

Does this happen for every audio file, or just one particular file?

Thanks for reply!
It happens for every file and (maybe) every magic file.

Ok, and are you using the Internal Speakers as your sound output device, or a different one?

Thank you
I can only choose 'Display Audio.'

Hmm, I'm not sure what that device is. Are you using an HDMI cable to pass audio to your monitor? Do other applications play sound properly?

Also, when you go to the "Audio MIDI Setup" application and select your output device, what does it say? Can you post a screenshot?
