Re: bluetooth speaker under NetBSD

[Ryo ONODERA <ryo%tetera.org@localhost>]

Hi,

I do not know much about btsco(4) audio device.

If you want to only play music. I recommend you should try bta2dpd(8).
It supports A2DP audio playback, however it does not support microphone.
If you use Bluetooth *speaker*, I suspect microphone support may be
out of your scope.

https://blog.onodera.asia/2017/10/how-to-use-bta2dpd8-with-bluetooth.html
show you how to play music with bta2dpd(8).
It may have redundant and/or incorect steps, however I can play music
with my Bluetooth headphones with this procedure.

And if you have USB audio device or webcam, you should use it with the same
USB receptacle. In my old case, USB host controller in my machine
did not work correctly with NetBSD's USB support code.
btsco(4) uses USB isoch transfer like USB audio or webcam.
If your USB audio device and webcam does not work properly,
your steps will not be successful in many cases.
Of course recent NetBSD's USB support code is much improved.
So this may not be a problem...

Thank you.
