Works for me, but maybe you do not have the volume filter, which is
part of the normalize module, which is GPL and requires a build with
--enable-gpl. You can also use the sox filter, which does not require
GPL:
<filter>
<property name="effect">vol 0.083</property>
<property name="mlt_service">sox</property>
</filter>
