[v2010] Audio files sometimes muted with 0ms TIME value?

[blazpal]

Hello again,

My simplified input file is now attached to this post. As you will see perhaps, the sound on the first trial is audible but remains mute on the second (DRT v.2010, Win 7). It is still ok on the old version of DRT (2008) and Win XP where it is perfectly audible on the two trials.

Thanks in advance for your help !
