Hi!
Before I did a reinstall due to Spotty not working, I used the Bluetooth without problem. This time around, I installed the bluetooth, changed the soundcard to pulse (which worked fine before), but now it doesn’t work. This is what it says:
```
E: [pulseaudio] daemon-conf.c: [/etc/pulse/daemon.conf:90] Invalid number of fragments '5\ndefault-fragment-size-msec = 2\n'.
E: [pulseaudio] daemon-conf.c: [/etc/pulse/daemon.conf:90] Invalid number of fragments '5\ndefault-fragment-size-msec = 2\n'.

```

Hi dumtratt,

Which image did you use? Please reboot your system and try again.
Please also check whether you have Shairport on Pulse and make sure that your device shows up green when heading to the Bluetooth plugin.

Also, make sure you have the current version of the Bluetooth plugin, you can update it by just installing the plugin from our website again.

I have the same problem as several people in this thread: When streaming music from Amazon Echo to RPI3/M2P, the Squeezebox server stops after 3-20 minutes. After disconnecting and reconnecting the BT link it works again for some time, but then it stops again.

When I stream my Amazon Echo via BT to an Ubuntu server not running M2P (with a loop from BT input loop to HDMI audio output) everything is stable for hours!

My assumption is that there is a bug in the M2P BT plugin! Whenever there is a short BT connection problem (which can always happen due to WiFi interference) then the plugin stops working.

@Heiner: Did you ever test your BT plugin with Amazon Echo running for several hours with a Wifi interference from neighboring access points?

Thanks and regards

Harald

Hi Harald,

No we have not been able to test this setup, yet.

As mentioned in the other thread, could you try running the setup without WiFi and deactivating it for a time, to narrow down the possible source of error?

Hi Heiner,

I have tested this: Wifi was deactivated (ethernet cable) and the distance between M2P/Raspi and Alexa was only about 40 cm.
Also with this setup the playback stopped after some time.

It would be good if you could try to reproduce the problem in your lab: Just stream for several hours music from Amazon Echo to your BT plugin.

Hi Harald,

Thank you for the follow-up. Could you share the Debug Info Log from the Bluetooth Plugin when the playback stops?

We will try to recreate the issue here, but long term sound testing is problematic in our office environment.

Hi Heiner,

Please find the debug info below.
The playback stopped after 35 minutes. I used no Wifi and the Beta-171123 SW.

Hi guys, i m a new user,my name is Antonio and i’m italian..so..sorry for my english,absolutly not perfect.
I m testing max2play on my configuration. For now i just have Raspberry Pi 3 (i ll order ALLO BOSS DAC this weekend) connected to a QNAP NAS which i have more of 500giga of music (mp3 and flac). I wanted try bluetooth addon cause i use bluetooth daily with AUDIOVECTOR’s speaker.
I want build a system of music for all the rooms of my flat, so i m interesting to resolve various very little problems i m having..and this is the first and more important.
My problem with bluetooth (i dnt know if it s a common problem) is that i can be able to connect the speaker, it plays for 5/10/30 mins (with frequently disturbes) and then it stopped to play until i restart all the system and i reconnect it again..and then always the same. I need to resolve this cause i must understand if i need a dac or not, cause if i ll be able to have a stable bluetooth i ll concentrate to another room of my flat. Tnx to everyone will help me…and still sorry if my english is not correct.

UPDATE: clearly i tested it even without bluetooth, with headphones connection, and it played music for hours and hours without any kind of problem. And i noticed that with Spotify Connection Server and Bluetooth i have problems too..but this is another problem. First better to think to the first.

Hello Antonio,

do you use internal wifi together with bluetooth or is wifi disabled within the RPi settings?

Regards,
Stefan

6. Dezember 2017 at 17:42 #32814

Hi Stefan, tnx for the answer. I use internal wifi ..and i used it connected to Ethernet with the same problems, but i have never disabled wifi, even using ethernet

6. Dezember 2017 at 17:46 #32815

Maybe it helps to disable wifi and use Ethernet only. I have read about problems if both modules are activated.

6. Dezember 2017 at 17:49 #32816

Ok..if u are so gentle to tell me how disable it i ll test it now

antonio81le

6. Dezember 2017 at 18:00 #32817

Maybe i Found. On Raspberry Settings there is the voice DISABLE WIFI..right?

So ist seems to be a driver problem which is only solvable with a new driver package…

Sorry, i am Linux noob. But what i see in your log, is a problem with LMS. The error message in google returns a lot of stuff 🙂

I saw many errors with Logitech Media Server too..but i don’t know if it is the problem. If i play music by headphone,for example, it works good..yes, it s slow, i dont like graphic..sometimes many music is not showed in my library (i ll try to see for these errors),but i dont know if there are others possibility to play bluetooth. I tried with Spotify Connect but no sound available..

Hey guys,

I read now for around 1h cross this forum trying solving my problem:

I just got the Pro-Licence because Max2Play + Bluetooth Plugin (as a reciver) would work perfectly for my whole house multi room sound system. I have to have BT because of sources which can’t be streamed via DLNA or Network Apps (Spotify etc.) like Audible from my smartphone.

On two RPi3 without any soundcard, with the newest 2.45 image from the website and BT Plugin up, running, paired and connected, I had the same issue: Sound was cracking, jumping some ms back and forth, buffer collapse and also reboot.

For me it sounded like wrong buffer parameters so I was trying to get information in the backend (SSH) or even reconfigure buffer.

While reading in the forum is saw this post:

Maybe it helps to disable wifi and use Ethernet only. I have read about problems if both modules are activated.

Without believing it would work this solved the problem on both of my RPi. Coming from the idea of a multi room wifi sound network, LAN is not working in my case.

Is this problem known, any (backend) workaround?

Nobody has some ideas about why bluetooth doesnt work?!

I was not able to solve the BT problem that I had (I used MAX2PLAY as BT sink/receiver – see above #32549).
I guess there is simply a bug in the MAX2PLAY BT plugin.
Meanwhile I am using SnapCast for my multi-room system. With SnapCast the audio playback is stable for hours when streaming via BT.

11. Dezember 2017 at 19:38 #32871

Could u tell me more about this? Can i use it with Max2Play ?
hanoba premium

12. Dezember 2017 at 10:14 #32878

Snapcast (https://github.com/badaix/snapcast/) is an open source synchronous multi-room audio player. It cannot be used with Max2Play.

Hi,
when trying to install the Bluetooth support, nothing happens.
After rebooting, the Bluetooth settings to add bluetooth devices does not show up. The Bluetooth page again just shows the button to „install bluetooth“.
