Hifiberry digi, und MPD alsa permission denied to dmix plugin

  • Hi

    having stretch on the raspberry

    a hifiberry digi card as sound


    aplay -l shows the card and aplay -L as well


    I adjusted asound.conf to have a dmix device.


    this dmix device can not be used by mpd.

    errormessage. permission denied to the device.



    If I run mpd as root it is working, but this can only be a workaround.


    mpd is a member of group audio


    I am running squeezelite as a service with this device without any problems.



    any idea how to the / check permissions.


    Thanks T
