Tested your sample with 0.24; and it's all working as expected..

However, I did find an unexpected behaviour ; because channels configuration
is set to 5.1 and the audio being played is 5.0 ; the audio is decoded then
re-encoded to 5.0 AC3 again if you have the upmixer enabled even though the
upmixer doesn't work on 5.0
