I investigated that and what I noticed is that at it happens at the precise
time where you have the transition between 2 source.

I can notice that at that exact time you have a discont buffer, which means
that "the buffer marks a data discontinuity in the stream. This typically
occurs after a seek or a dropped buffer from a live or network source." which
might be a beginning of a lead.

In playback the glitch does not happen and, if you do not encode the audio
stream while rendering (for example you can use raw audio in mkv), the glitch
does not happen.

I will check further how to solve that issue later.
