Yestoday I have seen this in the help:
BB OS audio management plugin
Library file: mmr-audiomgmt-plugin.so 
This plugin supports the audio: output URL, and has the following parameters: 
writer
The filter to use as the audio writer for audio: outputs. 

How can I get the mmr-audiomgmt-plugin.so and audioman ,I already have  the QNX6.6.0sdp and APP&Media but I cannot find 
these plugins.

There is a test program named player in QT5.2 SDK, When it runs, there is an error: cannot find audio:default,

Can you give me mmr-audiomgmt-plugin.so and audioman,and their configure files which are named mm-renderer.conf and 
audioman_default.conf?

thanks
