# From web admin portal, setup new wireless wan port for 5G and 2G separately:
# http://192.168.1.1/cgi-bin/luci/
### Network
### Wireless
### Scan
### Selected your existed SSID, Joining Network
### ## Replace wireless configuration = yes
### ## Create / Assign firewall-zone = LAN
### Go to Network/Interface
### Set the IP of wireless wan, as normal
Login into your MPD system, add the following block into the the mpd.conf file:
audio_output {
type "pulse"
name " Wifi Router"
server "IP_OF_WIFI_ROUTER:4713"
}
Now, you can find the “Wifi Router” option item, from Outputs/Server properties/M.A.L.P, suppose M.A.L.P apk installed android handset
To support play DSD dff file inrealtime mode, we must add dsdiff plugin in mpd config file.

# Normalization automatic volume adjustments ##################################
#
# This setting specifies the type of ReplayGain to use. This setting can have
# the argument “off”, “album”, “track” or “auto”. “auto” is a special mode that
# chooses between “track” and “album” depending on the current state of
# random playback. If random playback is enabled then “track” mode is used.
# See <http://www.replaygain.org> for more details about ReplayGain.
# This setting is off by default.
#
#replaygain “album”
#
# This setting sets the pre-amp used for files that have ReplayGain tags. By
# default this setting is disabled.
#
#replaygain_preamp “0”
#
# This setting sets the pre-amp used for files that do NOT have ReplayGain tags.
# By default this setting is disabled.
#
#replaygain_missing_preamp “0”
#
# This setting enables or disables ReplayGain limiting.
# MPD calculates actual amplification based on the ReplayGain tags
# and replaygain_preamp / replaygain_missing_preamp setting.
# If replaygain_limit is enabled MPD will never amplify audio signal
# above its original level. If replaygain_limit is disabled such amplification
# might occur. By default this setting is enabled.
#
#replaygain_limit “yes”
#
# This setting enables on-the-fly normalization volume adjustment. This will
# result in the volume of all playing audio to be adjusted so the output has
# equal “loudness”. This setting is disabled by default.
#
#volume_normalization “no”
