    I bought a Raspberry 3 with a HifiBerry Digi+ and a license for Max2Play some days ago.
    I am trying to set it up as „Starter: A simple audioplayer for internet radio and local music (mp3)“ with no luck.
    I Expanded the filesystem in a first step, then activated my license and set up the System with the „Starter“ option.
    After that I included an NFS share with some music and configured mpd to use it. Worked well as YMPD and an MPD Client show a filled database.
    When I am trying to play some songs nothing works. I can see the following in /var/log/mpd/mpd.log

    Oct 05 16:54 : client: [10] opened from
    Oct 05 17:05 : alsa_output: Failed to open "Max2Play ALSA Device" [alsa]: Error opening ALSA device "default:CARD=sndrpihifiberry" (snd_pcm_hw_params): Invalid argument
    Oct 05 17:05 : output: Failed to open audio output

    Any ideas what is wrong here. I tried to set up the HifiBerry with the free plugin and with the „Raspberry Settings“ plugin.

    This is quite frustrating as I bought this bundle in the hope to have an easy to set up package with Max2Play …

    Hello Spaetzle,

    Thanks for your request. Did you reboot the system after choose the HiFiBerry Digi+ in the HiFiBerry plugin menu?

    Best Regards

    Yes I did reboot the Raspi.

    As I tryed out many things I started again today:

      Downloaded m2p_rpi3_hifiberry_235_wps.img.zip, unpacked and put it on the SD Card
      started the PI
      Settings / Reboot – Expand Filesystem
      Settings / Reboot: Entered License Code, Changed Language to german

    Remark: Everything is in english althougt the interface shows that german is selected.

      Menu „HifiBerry“ – Selected Digi/Digi+.
      Selected: „Starter: A simple audioplayer for internet radio and local music (mp3)“ – Select this setup
      mounted a nfs share with music and changed set up of mpd to the mounted folder

    Now I opend a ssh connection to the PI and looked into /var/log/mpd/mpd.log. After stoping and restarting mpd with the webinterface I get the following output:

    Oct 11 11:44 : client: [0] closed
    Oct 11 11:44 : zeroconf: No global port, disabling zeroconf

    Any ideas what’s going wrong here?

    Hello Spaetzle,

    please try this. Go to the HiFiBerry menu. I think there is, at this time, the Hifiberry Digi/Digi+ the chosen sound card? Change it into none and save this configuration. After this, change it again into Hifiberry Digi/Digi+.

    We have test it and this solves the problem for the moment. We are working on this.

    Best Regards

    Hi Christoph
    OK. It is doing a little more. I can not see an more errors. But there is no sound.
    Is there a trick if I want to use the optical output. The PI is connected to the sound system with the optical output as I have no coax input at the sound system …
    And as it seems I can not use the volume control of mpd. The controller with the client software I am using (gmpc) is unavailable.
