heey hope someone can help me . unfortunately i cannot watch any video content with the bluetooth audio there is a 1 second delay and my wifi adapter is disabled can somebody help me ?

Hello,

Thank you for sharing this project. I am able to install bt-speaker on RPi and pair a device. But there are random short silences around every 3 seconds. and after 30 seconds I get this

I don't know if it's the software or my hardware that's faulty...
Whenever I connect to the Pi after it had been inactive for a while since last using it (eg reconnecting to the Pi the next day), it won't play any sound to my 3.5mm jack.
It still connects and the bluetooth works just fine, but it won't play any sound unless I completely reboot it.

Also, a sound indicating when the Raspberry has successfully connected to a device (and also to verify that it does still play sound) would be very helpful. I might just as well suggest an "auto-reconnect" feature while I'm at it, so my Pi would always connect itself if it finds any known device..

Thanks in advance, I really do like this project!

This is the best solution that I could find that works with the PI 3.
But the sound output is currently very low. Is there a way to boost the output volume?

I already have the volume at 100% and I noticed it is a common problem with ALSA.

i'm install bt-speaker on raspberry 3b,but i don't know how to work.

and at the dmesg

[ 1.982751] systemd[1]: Configuration file /opt/bt-speaker/bt_speaker.service is marked executable. Please remove executable permission bits. Proceeding anyway.

Hi

I get some rather annoying sound glichtes (snaps or crackles) when starting the audio playback on my phone (or when changing from one app to another). I notices that this wasn't a problem before the "broken pipe fix" was implemented.
I don't know much python and nothing about bluetooth audio streaming, but the noises dissapear when i remove the following line:

Without the fix for the broken pipe, my audio would stop playing after about 15 minutes. Connection would persist but it would just go silent.

Apparently, there is no other way to contact each other via Github. So, using this way:
I wrote another bluetooth daemon target at embedded and low-powered boards:
https://github.com/mincequi/cornrow

It is fully debianized and also has a built-in equalizer (can be remote controlled via app).
Since it is utilizing gstreamer, adding further codecs and other nifty filters should be easier to integrate.
Please, tell me waht you think and potentially we might join up forces here.

Thanks.

Best regards,
Manuel

Disclaimer: Really new at linux/raspberry pi

I installed bt_speaker yesterday and it played with out issues. Long story, but bottom line the pi was erased before I could back it up. Now with the same installation the audio quality is terrible. It stays connected but the audio grainy and seems to be playing faster short skips in audio. I am connected via ethernet.

Any advice would be helpful

Hey
I have certain questions and use cases

1. How can we uninstall this module?

2. This module will allow only audio to be streamed from one device. But is it possible to have multiple devices/phones to stay connected? That is Pi has knowledge of all active connected devices but through user action the Pi will switch connection and only play from one of them.
   For eg, user 1 plays audio, Pi switches connection to User 1 and accepts streams. If User 2 also play audio, Pi switches connection and accepts stream from only user 2.

3. Which also brings the question how many paired devices can it be made to remember?

4. Can we alter the pairing behaviour? Pressing physical buttons or adding pairing code?

5. I have a default ALSA device called dsp This applies system wide audio DSP. I assume by default the module will output any incoming stream through the default ALSA device, correct? No changes need to be made?

Sometimes it happens that despite successfully connecting no sound is playing. Looking at the logs I see:

Reconnecting does not help.
Restarting bt_speaker fixes this.
This seems to be happening mostly over night. At evening before everything works great and the next morning it doesn't. But it doesn't happen every night.

I don't no what exactly is causing the IOError, but I think it would be good to handle it gracefully.
For me just doing sys.exit(1) on such an error would be enough, as systemd will immediately restart the service and everything will be working again.

I am running bt-speaker on a Raspberry Pi 1B.
(I know this is not the officially supported Hardware, but it is working really great. Much better than the pulseaudio solution I tried before.)

Hi.
I am working on it in my car. I have a carpi with android auto etc. It works great, but my phone connects as a Headset with mic input. I deactivated it, because I have one in my car, but I would like the possibility to connect the output to kodi. So I could see what I am hearing, show visualisation, and maybe change to the next track etc.

Also the call input would be nice to accept it with the pi and make calls with it. This isn't very important to me, but would be nice and maybe others would like it.
Thanks

Hi:
The demon is running but I get no sound, my dmesg is filled with "Bluetooth: hci0: Frame reassembly failed".

I'm trying to setup my system so that it will play the output of the bluetooth streamer to a SPI DAC on the raspberry pi (pHAT DAC). Their one line installation for the dac broke the bluetooth setup. So then I went through line by line to figure out what exactly was breaking things. It turns out that the only thing that breaks the bluetooth speaker is commenting out dtparam=audio=on in /boot/config.txt. When that is commented out, the rpi will still broadcast, but I will be unable to connect to it with my iphone over bluetooth. Removing the commented line fixes the problem. I'm running Raspbian Jessie and have a Raspberry Pi W Zero. This was done with a fresh install of the most recent version of Jessie.

Not sure what this line is loading that is essential to this library but for some reason it seems to break something.

Hi there,

for a relatively special use case I’m looking for a device which can act as bluetooth speaker for two senders at the same time with (smart) mixing of the two signals before output.
Any educated guess if this would be possible by slightly extending this project?
I would start with modifying the class AutoAcceptSingleAudioAgent to AutoAccept2AudioAgent, but I have no idea whether the bluetooth stack would allow a second input device.

When I check the sudo systemctl status bt_speaker.service I see this error. It seems there are some permissions issues for the btspeaker user?

Hello,

I have a raspberry pi 3 B+, I did a fresh install and run the script as mentioned in documentation.

But no device was found on my Mac or my Iphone.

The config.ini is

Did I miss something ?

For some reason when i run install.sh as root, the package install aborts like this:

Do you want to continue [Y/n] Abort.

Needed for RPi3 Model B

(new feature)
Today playing is accomplished with

aplay -f cd -

But say that we would like resample the 44.1k audio stream before piping to a CODEC, for example at 96k.

SoX allows for advanced audio manipulation and piping. Where would one start in order to add such functionality to bt-speaker? Is it at all possible to parse more elaborate commands from the config file?

Audio is laggy while android is connected ith wifi connected (wifi of android device).

Hi there,
i'm getting no audio at all from my external sound card, the cardindex option seems to do nothing. That's my aplay -l

Thank's for a terrific project!!! Now I would like to improve the audio output and installed the DAC+ from Hifiberry. I dont really understand how to use the alsa config in order to allow for volume control. Maybe not right to post this here, but eventually others will find some clues for how bt-speaker can be setup with a DAC on latest Rasbian.

My setup:
RPi 2 b+ with BT dongle: DIGITUS Bluetooth® 4.0 Tiny USB Adapter
Rasbian 2017-11-29-raspbian-stretch-lite.zip

If I needed to send 2 way audio through for calls, I'm not quite sure where to even start could you point me at any resources you're aware of?

Hi all,

I recognized an issue in a RPI3 using bt speaker to use the Pi as an audio transceiver. First of all, bt-speaker is working fine without problems. I do not use the builtin WLAN module to avoid the sound problems.

After some time, even if not used, the python-process of bt-speaker constantly causes high cpu usage (100% on one core). How can I help to investigate?

Regards,

Hi , I tried to start the daemon manually and i get thi stuff ( raspberry 3 ).
I see the device on my phone and it tries to connect to it but suddenly the connection drops..

any idea ?

thanks

Marco

Is there a function to connect to a device?

I rewrote the handler and after no device is connected it try's to reconnect to the last connected device but the method to connect to a device using the uuid seems to not exist?

Installed a HiFiBerry DAC+. After a little work, got sound to stream flawlessly through bluetooth.

My issue is that with the onboard sound, everything worked. Now the connect/disconnect audio doesn't play. I'm not sure what to do. Disabling the onboard sound seems to break bt-speaker, and I've tried a bunch of other suggestions, to no avail.

thanks for the great job!
I installed it successfully on my i686 pc (codec use PLATFORM = mmx).
it is possible to open audio device only when used? when bt device is connect and play?

Help, I can't install

When running on a Raspberry I encountered following problems with bt-speaker:
the service crashed with a python stacktrace and ceased working. The connection between bt-speaker and client was still running. Only restarting bt-speaker fixes the issue.

How to repeat:

• use alsa dmix plugin
• start mpd and bt-speaker
• connect to bt-speaker with client
• start playing music on mpd and stop it

Bt-speaker crashes with this messages repeatedly.

I used it with dmix for multiple sources and combined both stereo channels to mono on each output channel. Config

I tried to get this up and running and when the service is about to start i get following message.
Am I missing something?

Hi, I installed your project on my pi zero w but now I am having a problem. I can find and connect to it only when the usb audio card is not set as default audio device and without it I can not sound it :( , what can I do to solve it?
Thanks you for your work anyway

This is really handy and works great on a Pi Zero W. One question. For my car I'd like to require connecting clients to enter a pin because, sometimes we can't have nice things. I've been playing with this block of agent.py but haven't figured out the magic. Thoughts? It's not critical- I'll dig into DBUS if I need to. Thx!

                 auto_authorize_connections=True,
                 default_pin_code='0000',

Whenever I connect with my phone the start volume is too low. I always have to manually turn up the volume.
I am not sure if this is an android, RPi1 or bt-speaker -specific problem.
Would it be possible to specify an on-connect-default volume in the config, or even better store the last volume and apply it at subsequent connects?

Thank you for this piece of software, it's just fantastic. Love the simplicity, especially compared to other solutions! 😊

I've got a strange issue with AVRCP from my iPhone running iOS11:
I always output the sound through the audio jack, so I set cardindex = 1. If I connect from macOS I can set the volume remotly without problems. With the iPhone I can also set volume, but if its set to 48% or above output switches to HDMI (iPhone jumps 6%, from 42>48% on 1 button press). When I set to 42% or lower it switches back to jack since I've set that in config.

Any idea where to search for debug?

I am running Linux raspberrypi 4.14.52-v7+ #1123 SMP Wed Jun 27 17:35:49 BST 2018 armv7l GNU/Linux on a Pi 3 Model B.

Everything in the logs looks normal and I am able to pair two Android devices and transmit audio.
However, no audio is played on the Pi. I tested with another audio source (Youtube) directly on the Pi and it works without issues.

What else can I check?

In my setup I discovered a very strange behaviour: bt-speaker works fine on the Raspberry Pi 3 (USB Audio, USB Bluetooth Adapter, Wi-Fi and internal Bluetooth disabled).

However when I try to connect from a Mac (macOS), the sound is very distorted. This cannot relate to the known Raspberry Pi Bluetooth/Wi-Fi issues (as other devices work), but may be a missing piece in the decoder code.

When I change the play_command to cat > /tmp/out I can save the decoded stream and later play with aplay -f cd /tmp/out. I’ll attach the file, which may give an indica
tion what goes wrong here… (you can play them with aplay -f cd out.pcm)

(Playing A2DP via BlueALSA/BlueALSA-aplay works also fine, for all devices including the macOS ones)

it connects, and play the welcome sound
and when trying to play audio : nothing to hear
any idea ?

Hello,

It would be nice to allow support for aac and/or aptX
https://github.com/mstorsjo/fdk-aac
https://github.com/Arkq/openaptx

edit: some kind of implementation is here: https://github.com/Arkq/bluez-alsa

Thanks!

I tested this with my phone and it worked fine but when I pair my Amazon echo dot, the playback is interrupted once every one to two seconds. Has anyone else experienced this or know a fix?
I know it's not a signal strength issue because the two are right beside each other. Thanks!

When using bt-speaker (i.e. when I have connected my phone to play music), if I move the mouse my whole rpi hangs and needs to be unplugged to reboot.

I have multiple UPnP players but I miss Bluetooth as an input audio stream. What is the easiest way to not play the audio locally on the Pi but provide it as HTTP stream? Then I can instruct one or multiple players to use that stream as local 'internet' radio

https://wiki.videolan.org/Documentation:Streaming_HowTo/Command_Line_Examples#HTTP_streaming

Hello, first off all: Congratulations, great work! I haven't seen any other implementation of A2DP that needs nearly no configuration. The only problem, I currently have is that I can't control the ALSA volume on the iPhone. I tested it with an iPhone SE (iOS 10.3.1) and iPhone touch 4G (iOS 6.X). However, it works perfectly fine on an Android phone. So I assume the configuration is correct. Do you have any idea, what the problem is?

would it be possible to add simple media controls like play/pause and next/previous track?

I missed conversation about my pull request! The reason I hooked into the code for implementing Sonoff was actually to implement timeout for calling script and add functionality to make HTTP call as many relays controlling power support it. Mainly this was because I didn't wanted bt-speaker to turn off power immediately someone disconnect from BT. Implementing that within scripts require to run them as another daemons or have a timeout functionality within controller itself. Would you agree to improvement to run script or call http with timeout value instead?

Hello,

Great project. I am trying to tinker with this to work for my needs.

One issue I have run into is that the service which streams the audio appears to block the alsa sink device from other sources. When I connect to the speaker, I get the following output:

Device connected. device=/org/bluez/hci0/dev_14_A3_64_58_DB_F9
Hiding adapter from all devices.
aplay: main:722: audio open error: Device or resource busy

Similarly on disconnect:

Device disconnected. device=/org/bluez/hci0/dev_14_A3_64_58_DB_F9
Showing adapter to all devices.
aplay: main:722: audio open error: Device or resource busy

But I can play audio just fine (except for the WiFi-caused underruns in issue #4 ).

Here is my /etc/bt_speaker/config.ini file:

[bt_speaker]
play_command = aplay -D plug0 -f cd -
connect_command = aplay -D plug0 /usr/share/sounds/freedesktop/stereo/service-login.wav
disconnect_command = aplay -D plug0 /usr/share/sounds/freedesktop/stereo/service-logout.wav

[bluez]
device_path = /org/bluez/hci0

[alsa]
mixer = PCM

Let me know what I can try.

When the default btspeaker user is used on the latest Raspbian (Stretch), the user does not have enough permissions on the DBUS. Running the script as root works perfect.
