DSD content in wavpack plays as PCM on DSD capable DACs

Bug report

Describe the bug

DSD content in wavpack plays as PCM on DSD capable DACs. Tested two different DSD capable DACs. When playing DSF file then DACs displays "DSD" but when playing DSD content from wavpack file then DACs displays PCM and sampling rate. The same wavpack files played from jriver or neutron players on the same DACs are played as "DSD" (not an issue with the wv file). The "dop" is enabled in MPD config.

Expected Behavior

Wavpack with DSD content should be played as DSD on a DSD capable DAC.

Actual Behavior

Wavpack with DSD content is played as PCM on DSD capable DAC.

Configuration

# An example configuration file for MPD.
# Read the user manual for documentation: http://www.musicpd.org/doc/user/

# Files and directories #######################################################
#
# This setting controls the top directory which MPD will search to discover the
# available audio files and add them to the daemon's online database. This
# setting defaults to the XDG directory, otherwise the music directory will be
# be disabled and audio files will only be accepted over ipc socket (using
# file:// protocol) or streaming files over an accepted protocol.
#
music_directory     "/Volumes/cirrus_mirrored/Music"
#
# This setting sets the MPD internal playlist directory. The purpose of this
# directory is storage for playlists created by MPD. The server will use
# playlist files not created by the server but only if they are in the MPD
# format. This setting defaults to playlist saving being disabled.
#
playlist_directory      "/Volumes/cirrus_mirrored/Music/Playlists"
#
# This setting sets the location of the MPD database. This file is used to
# load the database at server start up and store the database while the
# server is not up. This setting defaults to disabled which will allow
# MPD to accept files over ipc socket (using file:// protocol) or streaming
# files over an accepted protocol.
#
db_file         "~/.mpd/mpd.db"

# These settings are the locations for the daemon log files for the daemon.
#
# The special value "syslog" makes MPD use the local syslog daemon. This
# setting defaults to logging to syslog.
#
# If you use systemd, do not configure a log_file.  With systemd, MPD
# defaults to the systemd journal, which is fine.
#
log_file            "~/.mpd/mpd.log"

# This setting sets the location of the file which stores the process ID
# for use of mpd --kill and some init scripts. This setting is disabled by
# default and the pid file will not be stored.
#
# If you use systemd, do not configure a pid_file.
#
pid_file            "~/.mpd/mpd.pid"

# This setting sets the location of the file which contains information about
# most variables to get MPD back into the same general shape it was in before
# it was brought down. This setting is disabled by default and the server
# state will be reset on server start up.
#
state_file          "~/.mpd/mpdstate"
#
# The location of the sticker database.  This is a database which
# manages dynamic information attached to songs.
#
#sticker_file           "~/.mpd/sticker.sql"
#
###############################################################################

# General music daemon options ################################################
#
# This setting specifies the user that MPD will run as. MPD should never run as
# root and you may use this setting to make MPD change its user ID after
# initialization. This setting is disabled by default and MPD is run as the
# current user.
#
#user               "nobody"
#
# This setting specifies the group that MPD will run as. If not specified
# primary group of user specified with "user" setting will be used (if set).
# This is useful if MPD needs to be a member of group such as "audio" to
# have permission to use sound card.
#
#group              "nogroup"
#
# This setting sets the address for the daemon to listen on. Careful attention
# should be paid if this is assigned to anything other than the default, any.
# This setting can deny access to control of the daemon. Not effective if
# systemd socket activation is in use.
#
# For network
bind_to_address     "127.0.0.1"
#
# And for Unix Socket
#bind_to_address        "~/.mpd/socket"
#
# This setting is the TCP port that is desired for the daemon to get assigned
# to.
#
port                "6600"
#
# Suppress all messages below the given threshold.  Use "verbose" for
# troubleshooting. Available setting arguments are "notice", "info", "verbose",
# "warning" and "error".
#
#log_level          "notice"
#
# Setting "restore_paused" to "yes" puts MPD into pause mode instead
# of starting playback after startup.
#
#restore_paused "no"
#
# This setting enables MPD to create playlists in a format usable by other
# music players.
#
save_absolute_paths_in_playlists    "no"
#
# This setting defines a list of tag types that will be extracted during the
# audio file discovery process. The complete list of possible values can be
# found in the user manual.
#metadata_to_use    "artist,album,title,track,name,genre,date,composer,performer,disc"
#
# This example just enables the "comment" tag without disabling all
# the other supported tags:
#metadata_to_use "+comment"
#
# This setting enables automatic update of MPD's database when files in
# music_directory are changed.
#
auto_update "yes"
#
# Limit the depth of the directories being watched, 0 means only watch
# the music directory itself.  There is no limit by default.
#
#auto_update_depth "3"
#
###############################################################################

# Symbolic link behavior ######################################################
#
# If this setting is set to "yes", MPD will discover audio files by following
# symbolic links outside of the configured music_directory.
#
#follow_outside_symlinks    "yes"
#
# If this setting is set to "yes", MPD will discover audio files by following
# symbolic links inside of the configured music_directory.
#
#follow_inside_symlinks     "yes"
#
###############################################################################

# Zeroconf / Avahi Service Discovery ##########################################
#
# If this setting is set to "yes", service information will be published with
# Zeroconf / Avahi.
#
#zeroconf_enabled       "yes"
#
# The argument to this setting will be the Zeroconf / Avahi unique name for
# this MPD server on the network. %h will be replaced with the hostname.
#
#zeroconf_name          "Music Player @ %h"
#
###############################################################################

# Permissions #################################################################
#
# If this setting is set, MPD will require password authorization. The password
# setting can be specified multiple times for different password profiles.
#
#password                        "password@read,add,control,admin"
