I am new to PulseAudio. As per my requirement, I need my audio output to be routed to either connected speaker, Bluetooth speaker, or both.

I am able to play the media file on speaker, or Bluetooth headset individually, however, I am not able to play on both.

I tried combining the two sinks, however, it always throws me the error:

Failure: Module initialization failed

Here's is the code snippet:
root@raspberrypi3:~# pactl list short sinks 1 palerts module-null-sink.c s16le 2ch 44100Hz SUSPENDED 2 pfeedback module-null-sink.c s16le 2ch 44100Hz SUSPENDED 3 pringtones module-null-sink.c s16le 2ch 44100Hz SUSPENDED 4 pmedia module-null-sink.c s16le 2ch 44100Hz SUSPENDED 5 pdefaultapp module-null-sink.c s16le 2ch 44100Hz SUSPENDED 6 peffects module-null-sink.c s16le 2ch 44100Hz SUSPENDED 7 pvoicerecognition module-null-sink.c s16le 2ch 44100Hz SUSPENDED 8 ptts module-null-sink.c s16le 2ch 44100Hz SUSPENDED 9 pndk module-null-sink.c s16le 2ch 44100Hz SUSPENDED 11 alsa_output.0.analog-stereo module-alsa-card.c s16le 2ch 44100Hz SUSPENDED 13 bluez_sink.FC_58_FA_F3_07_6F module-bluez5-device.c s16le 2ch 44100Hz SUSPENDED

For music playback: 

root@raspberrypi3:~# paplay abc.wav -d alsa_output.0.analog-stereo  
root@raspberrypi3:~# paplay abc.wav -d bluez_sink.FC_58_FA_F3_07_6F

Both work as per expectation.

However the problem is with the following statement: root@raspberrypi3:~# pactl load-module module-combine-sink sink-name=combine sink_properties=device.description=Combined slaves=alsa_output .0.analog-stereo,bluez_sink.FC_58_FA_F3_07_6F Failure: Module initialization failed

I tried cleaning ~/.pulse directory, Commenting module-suspend-on-idle, but nothing seems to be of any help. Any pointers will be of great help.

Figured out the reason why it was not working. On checking the logs of pulseaudio, I found that it was not able to find the module-combine-sink library. I copied the libraries manually in /usr/lib/pulse-9.0/modules, restarted the pulseaudio, and it started working as expected, i.e. audio routed to both devices.
