DAC+ MPD Mixer Problem

Hi Guys,

I am running a DAC+ and MPD on a Pi 3B for several weeks now without problems.

Yesterday I updated the Pi and since then I can´t access the digital Mixer in Alsa via MPD.

pi@raspberrypi:~ $ mpc volume 10
error: problems setting volume

I did not change anything in the config files

/etc/asound.conf

pcm.!default  {
 type hw card 0
}
ctl.!default {
 type hw card 0
}

aplay -l

**** List of PLAYBACK Hardware Devices ****
card 0: sndrpihifiberry [snd_rpi_hifiberry_dacplus], device 0: HiFiBerry DAC+ HiFi pcm512x-hifi-0 []
  Subdevices: 0/1
  Subdevice #0: subdevice #0

/etc/mpd.conf

audio_output {
            type        "alsa"
            name        "HifiBerry"
            device        "hw:0,0"    # optional
            format        "44100:16:2"    # optional
#          mixer_type      "hardware"
#          mixer_device    "default"    # optional
            mixer_control    "Digital"        # optional
#          mixer_index    "1"        # optional
}

uname -a

Linux raspberrypi 4.4.9-v7+ #884 SMP Fri May 6 17:28:59 BST 2016 armv7l GNU/Linux

When I open Alsamixer via console I can access and change the digital mixer.

Any idea what changed with the update?
