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.
