Hi pd community,

I'm using pure data on a raspberry pi 3+ for a project. I have bluetooth configured properly on it. I can send regular audio to bluetooth speaker connected, but the preferences -> audio in PureData doesn't show the bluetooth speaker. It only shows internal audio card or if I have a USB audio card, that shows too. But no bluetooth device.

How do I configure that? Do I need to use jack or something to route audio to bluetooth for Pd?

Do I need to get a newer pd version? Is this sort of bug because on my computer it shows the bluetooth devices in preferences.

Any suggestions.

My experience with Bluetooth audio in Linux has been:

• JACK has zero tolerance for the audio driver ever being late -- expect crashes or system lockups if you try to route audio from JACK to Bluetooth. That is, just don't.

• PulseAudio's support for BT audio is pretty good -- the "regular audio" that you spoke of. Audio production apps typically bypass PulseAudio, in which case BT audio may simply not be supported for them. That is, I expect you'd hit the same problem with SuperCollider, Audacity, Ardour, VCV Rack etc etc etc.

I'm not aware of a solution... That's not to say that there absolutely isn't one, but the Linux audio space is not unified as it is in Mac so audio device support may not be universal.
