[USB-Audio - Cambridge Audio DAC100 USB 2, playback] Playback problem

[Kev Bowring]

Using 4.11.0-10.15 kernel from -proposed playback fails using this mpd.conf

##Pulseaudio
#audio_output {
# type "pulse"
# name "Local MPD"
# server "127.0.0.1"
#}

##Alsa
audio_output {
        type "alsa"
 name "Cambridge Audio DAC100 USB 2 - USB Audio"
 device "hw:1,0"
 auto_resample "no"
 auto_format "no"
 auto_channels "no"
 replay_gain_handler "none"
 mixer_type "none"
}

If I reboot into 4.11.0-9.14 then playback with alsa works.
