Super! I will change the target of the log file yes (I saw 
Do you know the error message or a keyword for the drop-outs to find 
them in the logs?
What is the “log-level” to show them? (if I am not wrong, “notice”, 
which is “2”, is the default)

You can confirm any problem similar to a drop-out (= which modifies the 
value of the sound whereas it should not) is logged if it is the 
PulseAudio’s fault?
