[pulseaudio-discuss] Couldn't get stream from bluetooth headset

[Shinnosuke Suzuki]

Dear Tanu,

Thank you for advice.

I didn't resolve my issue, but I got cause of error in stream callback in
the
PA_STREAM_FAILED state.
 pa_context_errno : Access denied
 pa_context_errno(pa_stream_get_context) : Invalid argument
I got PA_STREAM_FAILED after PA_STREAM_CREATING in the stream callback.

Best Regards,
Shinnosuke Suzuki
