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
