Getting "Failure: Module initialization failed" error

Question

I have created a script file ( approximately 3-4 months before) capturing the live audio and it worked fine we are able to capture the live audio and also can hear from the headphone.

Here is my script file

#!/bin/bash

function set_live_audio {
        #get the sink name
        sink=$(pactl list short sinks | grep "alsa_output" | awk '{ print $2 }' | head -n1)

        #get bluetooth sources
        pactl list short sources | grep "bluez_source" | awk '{ print $2 }' | while read bluetooth_source
        do
                if [ ! "$(pactl list short modules | grep source=${bluetooth_source} | head -n1)" ]; then
                        index=`pactl load-module module-loopback source=${bluetooth_source} sink=${sink} latency_msec=1 source_dont_move=yes`
                fi
        done

        #get alsa sources
        pactl list short sources | grep "alsa_input.usb" | awk '{ print $2 }' | while read alsa_source
        do
                echo $alsa_source
                if [ ! "$(pactl list short modules | grep source=${alsa_source} | head -n1)" ]; then
                        index=`pactl load-module module-loopback source=${alsa_source} sink=${sink} latency_msec=1 source_dont_move=yes`
                fi
        done
}

while true; do
        set_live_audio
done

Today I again ran this hand, but I didn't catch any live audio. I get "Failure: Module initialization failed" error. I tried to resolve this error but no luck.

Here is my output of pactl list short sources command (with bluetooth on)

0   alsa_input.usb-046d_0823_D81A0330-00-U0x46d0x823_1.analog-stereo    module-alsa-card.c  s16le 2ch 32000Hz   RUNNING
6   alsa_input.usb-046d_0823_4B709030-00-U0x46d0x823.analog-stereo  module-alsa-card.c  s16le 2ch 32000Hz   RUNNING
10  bluez_sink.00_1D_DF_44_DB_A6.monitor    module-bluetooth-device.c   s16le 1ch 8000Hz    RUNNING
11  bluez_source.00_1D_DF_44_DB_A6  module-bluetooth-device.c   s16le 1ch 8000Hz    RUNNING

So how can I resolve this error.

Answer 1

Restart PulseAudio (killing the existing daemon if needed):

pulseaudio -k

Load the PulseAudio module that provides an ALSA sink for Bluetooth devices:

sudo pactl load-module module-alsa-sink device=bluetooth
