+This sets the default alsa audio device to be the USB DAC via a dmixer plugin (which can be used by multiple applications at once) using a modified period and buffer size and optionally mix to 48khz. 
+
+This will then be used by default by Shairport-Sync and any other applications using alsa.

 Note that some distributions (such as Volumio 2) don't use an asound.conf file by default, they instead specificy the hardware details directly in '/etc/shairport-sync.conf' and '/etc/mpd.conf' files so some more in depth modification is needed to override this.
