I have trying with dbus-send , and different music files and I found the following things:

-I can play music mp3 songs.
-I can't play .mp3 (from WyabdcRealPeopleTTS)
-I can't play .wav (from WyabdcRealPeopleTTS)

I did the test using the command:

dbus-send --dest=com.nokia.osso_media_server --print-reply /com/nokia/osso_media_server
com.nokia.osso_media_server.music.play_media
string:file://media/mmc1/musicfile.mp3

The WyabdcRealPeopleTTS files are very small and short duration, for example:
abandonment.mp3 (2,14 KB) 0:00:01 16kbps, 11KHz
sterilization.wav (12,7 KB) 0:00:01 88kbps, 8bit, 11KHz

Download WyabdcRealPeopleTTS/2.1.0/

If you have knowledge about dbus-send and say which parameter could be proper for these files, I will check and I will my results here.


If anyone is interested in see the code inside /usr/bin/stardict-wav-play.sh :

>>>
#!/bin/sh

if [ $# != 1 ]; then

exit 1

fi

run-standalone.sh dbus-send --dest=com.nokia.osso_media_server --print-reply \

/com/nokia/osso_media_server \
