sound.Player() only outputs on earphone, not BT device when connected

robot1125

I am using the sound library to play mp3 files. On a phone the output only happens on the small earphone speaker, not a BT device when connected. This happens regardless of if the mute switch is on or off.

In other words, I connect a BT speaker, and audio plays there fine from apps like Music or podcast apps. But if I play an mp3 file via sound.Player(), it continues to only play via earphone speaker.

Any workaround?

@robot1125 perhaps due to this Pythonista issue

@cvp Could be! Seems like the issue has been open since May, so doubt there will be a fix any time soon :(.

Unfortunately, I think you're right

@robot1125 could you check if, in IOS settings, Pythonista is authorized to use Bluetooth

In settings, scroll until Pythonista app is reached

@cvp Interestingly, Bluetooth isn't even on the list for Pythonista, much less being toggled off. I believe the only way for it to get there is for the app to request access to the resource.

Do you know how to "make" Pythonista request access to Bluetooth?

@robot1125 I think that I never have requested access to BT service. If I use one of samples of CB module doc, I see the list of discovered peripherals, without any problem.

@robot1125 found in Apple Support

If there's an app that you use with the Bluetooth accessory,
go to Settings > Privacy & Security > Bluetooth on your iOS or iPadOS device,
and make sure that you've turned on Bluetooth for the app.

@robot1125 did you check your setting explained in previous post?

And could you run this little script and post result

import cb

class MyDelegate (object):
    def did_update_state(self):
        # State was updated (e.g. Bluetooth powered on/off)
        pass

delegate = MyDelegate()
cb.set_central_delegate(delegate)
print(cb.get_state())
