[pulseaudio-discuss] Using native HSP support

[DaCosta, Alexandre]

The verbose log only shows the following : 
D: [pulseaudio] module-bluez5-device.c: Acquiring transport /org/bluez/hci0/dev_00_18_09_1F_F7_61/fd16
I: [pulseaudio] backend-native.c: doing connect
E: [pulseaudio] backend-native.c: connect(): Function not implemented

Any  idea on how to debug this ?

If connect() is failing with "Function not implemented", it looks like the kernel doesn't have the necessary support. Maybe the kernel needs to be rebuilt with different options.
