    Hi all,

    I successfully setup a bluetooth connection to my SB Roar speaker. When I manually connect and manually start a multisqueeze instance it works fine, but it will not auto connect.
    Here is what I did:
    – Turn off speaker
    – Reboot raspi
    – Turn on speaker
    => nothing happens.

    When I click „Connect“ on the max2play Bluetooth page, the speaker makes a sound and the bluetooth address turns green. But the multisqueeze instance is still inactive until I click „Start squeezelite“.

    I am using max2play 2.47 on a Raspi.

    Here is the DEBUG info from the Bluetooth page:

    Where does the LMSIP parameter come from? That’s the address to the old squeezeboxserver. Meanwhile I am using the squeezebox server on max2play. How do I get rid of this setting?

    Hi Clarenze,

    That should be Shairport’s advanced options‘ Shairport/Squeezelite automatic Audio-Switch.

    8. März 2019 at 8:19 #44712

    thanks, but that was only a side question. do you have an idea why bluetooth does not connect and why squeezelite instance #2 does not start?

    8. März 2019 at 16:44 #44715

    Sorry, the answer was half out the door yesterday.

    We’ve not had any experience with the SB Roar nor with the automatic switch on MultiSqueeze.

    Could you try changing the outputs to BT on Audioplayer and your primary player on MultiSqueeze to see if this makes a difference?

    8. März 2019 at 20:37 #44718

    no, it does not. the first problem is that BT does not auto-connect. the multisqueeze instance not being started is problem #2.

    11. März 2019 at 12:39 #44740

    The auto-connect function works in tandem with the BT device’s own protocol for connection. Some speakers need constant re-connection, some are completely open to all pairings, some require a code to be entered. As mentioned, we have not had any experience with the SB Roar but seems to be an advanced Bluetooth solution.
    Please try to do the apt-get update upgrade (takes a few minutes) through our Raspberry Settings to rule out any possible dependency issue with Raspbian’s packages (our BT solution is directly based upon the official Raspbian solution).

    Please also make sure the „Bluetoooth-Speaker“ player below the pairing list is not active or in autostart.

    Meanwhile, I will try to recreate the issue here with a Pi3B and Max2Play 2.47 image. Please let me know if there any other factors in your system (like LMS installed) that might also recreate.

    12. März 2019 at 9:26 #44749

    I did the upgrade and a reboot but the speaker still did not auto-connect. Then I did a manual connect and turned off the speaker again. After that the auto-connect worked. Also the second squeezebox instance was started automatically. But I don’t hear any sound. Squeezebox server shows that it is playing something on the bluetooth output, but the SB Blaster stays silent.

    Bluetooth-Speaker is not active and I don’t have anything special installed (only what you can configure through max2play).

    14. März 2019 at 20:44 #44769

    Do you have any more tips for me?

    Today I noticed that when Bluetooth is not connected and I play radio via the hifiberry output, the stream stops every couple of minutes. Also squeezeplayer will ignore my attempts to select „No synchronization“. I killed the blueooth squeezeplayer instance now. Hope that will help.

    15. März 2019 at 15:42 #44780

    Hi clarenze,

    Very odd. We’ve had a few RPi 3B+ whose Bluetooth connection was very unreliable. It also shares the same antenna as the WiFi connection, so using both can cause dropouts.
    If you have not yet, try using the BT pairing with ethernet connection and WiFi disabled.

    16. März 2019 at 9:01 #44781

    Thanks, but it still does not work reliably.
    Here is what I did:
    – connected ethernet
    – disabled WIFI
    – rebooted
    – turned on Bluetooth speaker
    => speaker connected, max2play started second multisqueeze instance
    – started radio stream on squeezeplay bluetooth channel
    => worked
    – turned speaker off
    => bluetooth connection turns red in max2play GUI; bluetooth multisqueeze instance stays; squeezebox continues to stream (seconds count up)
    – turned speaker on
    => bluetooth connection turns green; squeezebox continues to stream; no sound
    – stopped bluetooth squeezebox instance
    – started bluetooth squeezebox instance
    => sound starts playing on speaker

    So the problem seems to be that mulitsqueeze does not stop the bluetooth squeezeplayer, when bluetooth is disconnected.

    23. März 2019 at 8:43 #44857

    is it planned to fix this issue?

    25. März 2019 at 10:19 #44859

    Yes, we are currently looking into this issue specifically.

    We will keep the community up to date on our findings.

    27. März 2019 at 14:32 #44900

    Hi clarenze,

    Our bug fix is now live in the current beta. Here’s the announcement:

    Hello everyone,

    We are glad to announce that he have found a fix for the current bug in Bluetooth. It’s only available in our current beta at the moment. To get the fix on your device, do the following:

    – Head to Settings/Reboot and click the Beta Update button
    – When the update is finished, head to Bluetooth and „Uninstall Bluetooth“
    – Refresh the Bluetooth menu if necessary and „Install Bluetooth“
    – Reboot after the installation is finished

    Your system should now be able to connect to any Bluetooth device again.

    29. März 2019 at 21:03 #44931

    I did as you told but the behavior is still the same.

    1. April 2019 at 14:20 #44939

    Hi clarenze,

    We tested Bluetooth with the new fix on MultiSqueeze and did not encounter any errors.

    Please try running a new image, making a Beta update from the start and then installing Bluetooth to rule out any possible dependencies from previous installs as a possible source of error.

    14. April 2019 at 13:46 #45039

    Done. Still does not work. 🙁
    When I turn off and on the bluetooth speaker, the squeezelite instance isn’t stopped and apparently cannot reconnect to the speaker at a later point. So I have to manually stop and start the squeezelite instance.

    The re-install was a pain, btw, as the „Restore Settings from File“ function in the Squeezeplayer tab does not work. I only get „Upload NOT successful!“.

    15. April 2019 at 9:41 #45043

    Squeezelite should not be stopped by the speaker. The bluetooth output should remain active on one Squeezelite instance and the speaker should be able to reconnect when started. You can check the Bluetooth menu for the entry which should indicate trusted and paired and connected when active.

    Best backup option to get the whole system safed is to create an .img file with our image burner plugin, which you can burn or save onto another device. However, saving the LMS settings should also not be an issue. We recently upped the max file size because someone had a huge save-file, how big was yours? This might the issue here.

    20. April 2019 at 9:26 #45080

    The bluetooth output should remain active on one Squeezelite instance and the speaker should be able to reconnect when started.

    It is not able to reconnect. Apparently Bluetooth does not really work (yet?) on Max2Play – at least for me.

    23. April 2019 at 10:05 #45101

    It works here, however, I always reiterate how diverse Bluetooth issues can be.

    What happened when you tried to reconnect? Do you have other BT devices paired? Which version of BT does your speaker use?

    23. April 2019 at 19:21 #45123

    When reconnecting, the speaker makes a beep to indicate that it established a bluetooth connection and that’s it. No sound after that. Only when I kill and restart the squeezeplayer instance, it works again.

    I do not have any other bluetooth devices paired with the max2play box.

    How can I tell which bluetooth version my speaker is using?

    25. April 2019 at 14:56 #45144

    Hi clarenze,

    I think we misunderstood each other in reconnecting. The issue before was that you could not reconnect to the Bluetooth device at all. It indicated paired and trusted but never connected. This was fixed in the last beta update which has now gone live. The reconnection with the Bluetooth speaker is the point.

    To restart playback when abruptly shutting down the BT speaker is not possible as far as I know. However, if you restart the player (be it with a simple command HTTP command or a click from your smartphone) the playback should immediately be re-initiated.

    27. April 2019 at 8:43 #45157

    If I turn off and on the speaker and then stop and restart playback, I do not hear anything. The timer continues to count up, but all speakers (including the bluetooth) stay quiet. Until I stop and restart the squeezeplay instance.

    30. April 2019 at 11:51 #45176

    Yes, as mentioned this is because you remove an active component in the playback-system while playing to it.

    1. Mai 2019 at 9:46 #45196

    On 25 Apr. you said „if you restart the player (be it with a simple command HTTP command or a click from your smartphone) the playback should immediately be re-initiated.“
    But this does not work.

    Or am I doing it wrong?
    Here is what I did:
    1) turn on BT speaker
    BT speaker beeps to indicate that a connection is established
    2) configure squeezbox to synchronize the main output (hifiberry) with the bluetooth output and start a tunein stream
    the radio starts playing on both speakers
    3) turn off BT speaker
    radio continues on main speaker
    4) turn on BT speaker
    BT speaker beeps, then silence
    5) press pause, select a new radio stream and press play
    radio only plays on main speaker, BT speaker remains silent

    2. Mai 2019 at 13:36 #45205

    Hi clarenze,

    Not pause and play but restart, meaning „stop Squeezelite“ and „start Squeezelite“in Max2Play.

    4. Mai 2019 at 8:09 #45256

    Is it planned to fix this? Afaik you do get a notification, when a blutooth target disconnects, so you could easily kill the associated squeezeplayer.

    6. Mai 2019 at 13:22 #45279

    I’ll consult our head developer to see if there’s a feasible way to implement an automatic restart without causing further issues with other player configurations.

    14. September 2019 at 9:52 #47081

    Any news on this? It is kinda strange, that there is no „wife-save“ way to stream audio from your cellphone to max2play.

    16. September 2019 at 13:48 #47092

    Hi clarenze,

    The easiest and better quality solution for direct streaming is DLNA/UPNP or AirPlay. Both can be enabled in the Squeezebox Server and both are compatible with most apps and smartphones. Apps like AllConnect or BubbleUPnP are some of the most popular solutions for direct streaming.

    16. September 2019 at 18:02 #47097


    These days you get your content via streaming platforms like audible or amazon music. None of these support Airplay. You could use AirAudio to divert the Android sound output to an Airplay sink, but that requires root on your Android device.
