I made other tests.

After the receiver becomes silent, if I restart the receiver and not
the sender, I get the sound. If I restart the sender and not the
receiver, the sound does not return. So I think I have no problem in
the pipeline that sends the sound, it's the pipeline which receives
the sound that stops.

I guess the problem is in one of these elements.
I gave the parameters "latency = 60 drop-on-latency = true" to the
element "gstrtpjitterbuffer" to make sure my sound does not delay.

Someone sees a problem in my pipeline, or can point to any setting to
be applied?
Do you have an idea to help me diagnose what is wrong and what happens?

Thank you in advance.
