    What’s the correct way to get M2P working with Hifiberry Digi+’s Toslink audio output?

    I just did a clean install of the Hifiberry M2P image.
    I’m using the Rpi as a Squeezebox replacement.
    I have my LMS on another machine on my network.
    I’m using iPeng as the remote control.
    I’m using Squeezelite on M2P as the player (not sure if I should be?)

    Here’s the problem: I can access all of my files just fine, but I only get sound from the Pi’s 3.5mm headphone jack–no sound output at all from the Toslink output from the Hifiberry Digi+. I also can’t tell if the Hifiberry is receiving any audio–I only see one green light on the Digi’s board.

    My guess is I have not installed the Hifiberry Digi+ correctly or that I do not have the output configured properly in M2P. For example, Squeezelite does not work on its default setting (equal – equal), so I’m randomly choosing one of the other soundcard settings to get it to start. It does start if I choose plugequal, but that’s probably wrong. I’m referring to this menu:


    Thanks very much for any help!

    Also, if I try to activate Squeezelite with the default soundcard setting (equal – equal), I get this error:


    or sometimes this error (device not found)


    Thanks for any help!

    I have a similar problem with a digi+ headphone socket output.
    New Pi3 + HifiBerry Digi+ (jack socket version)
    Clean install of latest Max2Play
    No sound at all from Digi+ output – only from Pi’s own headphone socket.

    I’ve tried all the suggestions – disabled the Pi’s own output, disabled bluetooth, activated the USB soundcard in audioplayer advanced settings, rebooted several times – nothing.

    And now even worse Squeezelight won’t start – error message:
    „Trying to launch … NOT successful Click here to show detailed information
    squeezelite: pcm_params.c:170: snd1_pcm_hw_param_get_min: Assertion `!snd_interval_empty(i)‘ failed.“

    Any help out there please would be appreciated.


    I’ve mounted the HifiBerry using nylon spacers rather than metal ones. I hope all the conncections between Pi and HifiBerry are via the header pins and metal spacers are not required for a ground connection!
    Also the HifiBerry worked OK when it was in a Pi2, just not in my shiny new Pi3 🙁

    I’ve just set „Soundcard = sysdefault-snd_hifiberry_dacplus…“ in Squeezelight advanced settings (it was equal-equal)
    Not only does Squeezelight start, but there is great sound coming from the HifiBerry digi+

    I have no idea why or how or what it all means.

    Justink – Why not try this too and see if it works for you? Good luck.

    (I can go to sleep late but happy)

    Thanks for the update TGH, I will give this a try too!

    I’ve found there is a bug in latest max2play with squeezelite output device settings.

    1) I’ve installed max2play image with 7″ for 7″ display
    2) default device was set to alsa
    3) I’ve set Hifiberry Digi/Digi+ as soundcard output from Raspberry Settings
    4) max2play only adds dtoverlay=hifiberry-digi to /boot/config.txt but /opt/max2play/audioplayer.conf was not changed. Once I disabled Disable Build-In-Audio on RPI3 from max2play setting menu (which actually adds dtparam=audio=off to /boot/config.txt) squeezelite didn’t start at all as it was trying to use nonexistant sound device.

    This is bug and should be fixed. Is there any common bugzilla where to search and file new bugs ? I have plenty of problems with max2play and using forum to report these problems seems pretty crazy to me.

    Thank you

    Hello shamot,

    Thanks for your advice! You are right with this bug which you have found.
    We are working to solve this and in the next version it will be fixed.

    Thank you very much.

    Additionally thank you TJH for solve Justinks problem.

    Best Regards.

    I have the same problem. Is there a work around in the meantime?



    21. Oktober 2016 at 16:11 #23517

    @gand, have you tried this (TJH’s workaround above)?

    „I’ve just set “Soundcard = sysdefault-snd_hifiberry_dacplus…” in Squeezelight advanced settings (it was equal-equal)

    My workaround was to give up on the Digi+ and get the Hifiberry Dac Pro instead. RCA outs worked from that right away and everything has been working great ever since. I realize that’s not really a workaround but a capitulation strategy.

    Good luck!

    , thanks for your prompt answer/help.

    For now I downgraded to Version 2.35 and that solved my problem. I can now choose the Raspbery Digi+ card. I already have a DAC and just want a coax connection into the DAC.

    Hopefully this will be solved in the next version.

    I’ve got the exact same problem – my HifiBerry Digi+ is not recognized and the setting under Raspberrry Pi Settings cannot be saved.

    How can I roll back to the previous version?

    27. März 2017 at 15:02 #27872

    @ GTJ,

    Please dont forget to update Max2Play version to the latest one, which is 2.41, many problems could be solved by only an update, now there is no option to roll back to the previous versions.

    Thanks for your help but unfortunately nothing worked for me and had to revert back to picoreplayer which works out of the box in my case.

    I couldn’t get my Pi/Digi+ Pro to output sound from the coax connection of the DIGI+ no matter what I tried.

    Thanks anyway.

    @ gtj

    Sorry for that.
    but there is no problem with Hifiberry Digi +, we tested in our lab and it works fine.

    Best Regards,
