Audio not streaming?

[Heartland]

So i am trying to create a bluetooth speaker with the speakers I've already got and a bluetooth adapter on my pi. However the pi and my phone is now connected, however I cant get any audio to play. Does anyone know why or can help me?
thanks

If you don't know this it is easier to do this with wifi, and with wifi you can stream unpacked 24 bit hires audio, whereas with bluetooth your going to have to stream packed audio and it will not work out-of-the-box. Which OS are you using?

[Heartland]

already brought the bluetooth adapter so im doing it by bluetooth. Raspbain is the one im using.

Bluez 5. 28?

[Heartland]

i dont know what you mean, sorry? i installed something along the line of "blueman"

pairing the device is only a part of the process.

See the thread on bluetooth audio streamin

[Heartland]

i was following this project as well as a few others and have done all the steps to where audio should work. Thats where i realized something wasn't right.

[tpylkko]

are your speakers connected to the pi via an amp that inputs on HDMI? or are you using the analog audio out? Or maybe even something else?

[Douglas6]

Isolate the problem. Are you running PulseAudio systemwide? Can you play a local file with 'sudo paplay'? Does the phone show a 'use for media audio' under the paired device? With the phone connected and playing audio, does 'sudo pactl list sources' show the Bluetooth source? Do you have a udev rule (or other method) to load the loopback module? Does 'sudo pactl list modules' show the loaded loopback module? Does it show the proper source and sink?

Im using a 3.5mm audio connector. However i have tried plugging my apple headphones into the pi and i get no sound that way either.
When i typed

Code: Select all

sudo pactl list sources

it returned:

this is was while i was playing music.

OK, good, you have a Bluetooth audio source. To connect that to your audio out, try

Code: Select all

sudo pactl load-module module-loopback source=bluez_source.78_6C_1C_5A_CF_1D sink=0

That should get the sound playing. To make that automatic, see this post: http://www.raspberrypi.org/forums/viewt ... 13#p619713 and follow the instructions for setting up a udev rule, at the bottom of step 5 (the 'Finally (finally!)' step.)
Ignore the cron nonsense in that b.ramus post mentioned earlier.

That doesnt work sorry.

[Douglas6]

Does it return an error? What does 'sudo pactl list modules' show? Are you sure the phone is not paused? Your previous output showed 'SUSPENDED' like the phone was not playing audio.

[Heartland]

Code: Select all

sudo pactl list modules

returns

Code: Select all

Module #23
Name: module-bluetooth-device
Argument: address="78:6C:1C:5A:CF:1D" path=" /org/bluez/2149/hci0/dev_78_6C_1C_5A_CF_1D" profile="a2dp_source" auto_connect=no
Usage counter: 0
Properties:
module.author = "Joao Paulo Rechi Vita"
module.description = "Bluetooth audio sink and source"
module.version = "2.0"

I hope thats the right module, cant find a way to copy and paste something out of my remote desktop into my normal desktop on my laptop.
it doesn't return an error but a number which gets greater each time i run the command. Its not paused.

[Douglas6]

You should be looking for a module-loopback module with the same number as that returned by the pactl load-module command. Mine looks like this

Code: Select all

Module #14
        Name: module-loopback
        Argument: source=bluez_source.AA_BB_CC_DD_EE_FF sink=0
        Usage counter: n/a
        Properties:
                module.author = "Pierre-Louis Bossart"
                module.description = "Loopback from source to sink"
                module.version = "2.0"

Make sure the phone is trusted.

Code: Select all

sudo bluez-test-device trusted 78:6C:1C:5A:CF:1D

should return '1'. If it returns '0', do

Code: Select all

sudo bluez-test-device trusted 78:6C:1C:5A:CF:1D yes

Then disconnect your phone and re-connect.

[Heartland]

ok i have that module and has made the phone trusted, but i still cant get it to play any music!

[Douglas6]

OK, back to an earlier question. Does 'sudo paplay <local.wav>' work? You are using powered speakers, right? Check alsamixer to ensure that the volume is turned up. When you 'sudo pactl list sources', does the Bluetooth source show 'RUNNING' and not 'SUSPENDED'?

[Heartland]

So I did the alsamixer and it was down on 0, so I turned it up to 100. I did this on both bars was this right? I don't have any local files on my pi and as I'm a newbie to the pi, I don't really get how to get them. And yeah it says suspended when is paused and when its playing.

[Douglas6]

There is a test file on the Pi. I think it's at /usr/share/sounds/alsa/Front_Center.wav (I don't have my Pi to hand).

[Heartland]

ok. i don't know what that sound file is meant to sound like but all i can hear is a hissing sound when i play it, but that is an improvement when i just play songs from my phone to my speakers, over bluetooth. The hissing sound is only when the sound is playing as it stops when the sound is over.
