Subject: bluetooth device

Hi All,

I am using iMX6SL-eval board, running kernel 3.16.0-rc3-next-20140630,
PulseAudio 5.0, Bluez 5.20. I ran bluetoothd and pulseaudio as
follows:

/usr/libexec/bluetooth/bluetoothd -EC
/usr/bin/pulseaudio --system

I was able to connect to the device through my phone as well as
streaming music and the bluetooth able to capture the play/pause...


If I ran pactl list sources short, I got the following:

0 alsa_output.platform-sound.analog-stereo.monitor
module-alsa-card.c s16le 2ch 44100Hz SUSPENDED
1 alsa_input.platform-sound.analog-stereo module-alsa-card.c
s16le 2ch 44100Hz SUSPENDED
2 bluez_source.D8_D1_XX_XX_XX_XX module-bluez5-device.c s16le
2ch 44100Hz IDLE

Then, for pact list sinks short:

0 alsa_output.platform-sound.analog-stereo
module-alsa-card.c s16le 2ch 44100Hz SUSPENDED


I load pulseaudio module:

pactl load-module module-loopback
source=bluez_source.D8_D1_XX_XX_XX_XX
sink=alsa_output.platform-tas57xx.14.analog-stereo

I checked the logs for pulseaudio and I was getting an error:

Jan 01 00:27:09 localhost pulseaudio[283]: E: [pulseaudio]
module-loopback.c: No such sink.
Jan 01 00:27:09 localhost pulseaudio[283]: E: [pulseaudio] module.c:
Failed to load module "module-loopback" (argument:
"source=bluez_source.D8_D1_XX_XX_XX_XX
sink=alsa_output.platform-tas57xx.14.analog-stereo"): initialization
failed


Any idea?.

Regards,

John

You better ask this question in PulseAudio mailing list, btw usually
module-bluetooth-policy will take care of creating of loading the
loopback module but perhaps you don't have in your default.pa.
