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

[Shinnosuke Suzuki]

I set the second parameter of pa_stream_connect_record with NULL.
I could get PA_STREAM READY in the stream callback!

OK
 pa_stream_connect_record(s, NULL, NULL, 0)

NG
 pa_stream_connect_record(s, source, NULL, 0)
  (source : bluez_source.00_14_BE_8A_7B_FE)

I got a problem, but I can't understand mechanism.
I checked the pactl like this:
root at OpenWrt:/opt/ipkt/lib# pactl info list
Server String: /var/run/pulse/native
Library Protocol Version: 30
Server Protocol Version: 30
Is Local: yes
Client Index: 3
Tile Size: 4056
User Name: pulse
Host Name: OpenWrt
Server Name: pulseaudio
Server Version: 6.0-dirty
Default Sample Specification: s16be 2ch 44100Hz
Default Channel Map: front-left,front-right
Default Sink: bluez_sink.00_14_BE_8A_7B_FE
Default Source: bluez_source.00_14_BE_8A_7B_FE
Cookie: e5ae:1788

I used the second parameter of pa_stream_connect_record as a
bluez_source.00_14_BE_8A_7B_FE.
This is a same value of default source.
What is the difference on this?
