[pulseaudio-discuss] Bluetooth : A2DP and AVRCP is working fine , but HFP is showing working but No sound -Mic/Speaker ?

Fri Jan 29 05:32:07 PST 2016

Thanks Tanu , really appreciated for your support 

1. pactl set-card-profile bluez_card.F8_32_E4_FB_FD_28  headset_audio_gateway
then
Loop back is like this 
2. pacmd load-module module-loopback source=bluez_source.F8_32_E4_FB_FD_28 sink=alsa_output.usb-Jabra_Jabra_UC_VOICE_150_duo_000000000000-00-duo.analog-stereo

But I can listen in the headphone speaker whatever I 'm speaking over MIC  ( it seems loop back within the device)

Maybe you are lacking module-loopback between the bluetooth and alsa devices? The log messages that you attached contained something about module-loopback failing to load.
