    After having been away from M2P for a while, I decided to try it again.

    After an evening of trying out, searching the forum, rebooting, trying, rebooting, it’s time to post here.

    Tried MPD first, on a random radio station. Result: sound!
    Activated my license, installed the spotify connect plugin. Result: all looks OK regarding spotify, except there’s no sound.

    Some more details:

    Version 2.47
    Raspberry PI B+
    License Activated
    HifiBerryDAC+ (B+/PI2/3)

    MPD not started by default; nothing else running that would block Spotify output (but if there’s a way to check & know for sure, please let me know).

    When starting MPD, I get sound when the following settings are present:
    Use USB-DAC: not checked
    Sound device: default – default,
    Also works when set to: sysdefault – snd_rpi_hifiberry_dacplus (CARD: sndrpihifiberry)
    Audioformat: 192000:24:2
    Mixer Device: hw:1
    Mixer Control: Digital

    DEBUG info of MPD (still contains lots of Failures, even though it works?!?):

    Then, I stop MPD and move on to spotify connect…
    Using spotify on my phone, I can connect to max2play, I can start music, but I don’t hear anything on the max2play.

    Settings on spotify connect:
    Output Device: hw:sndrpihifiberry
    (Other possible choice ALSA, but also that does not give any sound)
    Mixer Control: empty
    (if I fill in Digital, restart of spotify is not successful; DEBUG logging doesn’t show why).
    Command Line Options: empty
    Spotify/Squeezelite automatic Audio-Switch: empty or IP. Although I don’t have squeezelite running, I’ve tried both empty and with the IP address of my m2p raspberry. No difference, still no sound.

    DEBUG output of spotify connect:

    Again, nothing strange, nothing useful, as far as I can see.
    But alas, no sound…

    Some more output/settings:

    pi@max2play:~ $ aplay -l

    slave {
    pcm „plughw:0,0“;
    }
    hint {show on;description „Equalizer for plughw:0,0“}
    }

    First section was not present initially, tried without and later with these extra lines at top:

    pcm.!default {
    type hw card 1
    }

    What could be the problem here? And what other logging or settings do you want me to share to get to the bottom of this?

    Hi kraker,

    Please check the Raspberry Settings and see build-in audio is deactivated. If so, add „hw:0“ to the command line options and save, reboot and try again.

    Hello Heiner,

    Thanks for the response. Unfortunately, still no sound after trying that.

    /opt/spotifyconnect/librespot –name max2play –disable-discovery –cache /tmp –bitrate 320 –username *** –password *** –device hw:sndrpihifiberry hw:0 –onevent /opt/spotifyconnect/onevent_switch.sh

    This results in two hw: devices in the command line, by the way, which may not be what you had in mind?

    Any other thoughts on this?

    Somehow, the automatic player switch seems to be triggered. Do you have a value in this field on Spotify Connect?

    Also, please check all audio players and remove autostarts where they are active.

    Okay, removed the automatic player switch, rechecked that no other audio player is running.
    I was about to say: still no sound, when I noticed, far away in the distance, some sound. Turned up the volume, and yes, spotify IS playing (and may have been playing from the beginning), only the volume is absurdly low.

    So now the question becomes, why is that, and how can that be fixed? Again, if I try MPD, volume 12 on my receiver is already louder than I would normally play it. For Spotify, I can crank it up to about 50 to get to that same level.

    Copy and paste the mixer device selection from mpd to your Spotify Connect, save and reboot.

    Please copy the debug from Spotify Connect again if the problem persists.

    Found it, while looking at the DEBUG output, I noticed the –initial-volume option for librespot.
    Added --initial-volume 100 to the Command Line Options, didn’t turn back the volume on the receiver and was blown off my chair 😉

    Yes, it works now. Even after reboot, even after removing hw:1 from the command line options. All that was needed was the --initial-volume option. Case closed 🙂

    Update: fwiw, –initial-volume 90 brings it more in line with the DAB volume, but that’s fine-tuning.

    Hi kraker,

    Thanks for the quick follow-up! 🙂
