WARNING: Failed to set media volume (Unspecified error)
 

hi all,
i use the following sample code:

sound = viz.addAudio('bach_air.mid')
sound.loop(viz.ON)
sound.volume(.5)
sound.setTime(3)
sound.setRate(2)
sound.play()


and it will show me this error:
WARNING: Failed to set media volume (Unspecified error)
Please help me.
Thank you so much.

This seems be to be an issue specific with the midi format. It should work if you convert the file to another format.

hi Jeff,
but my project require only midi format.
Is there other way to adjust volume for midi file?
Thanks.
