The title of this thread and the description in the post do not seem to match each other. @guillaumerenaud, can you please clarify if the issue youa re having is of a Crashing Desktop Environment or a Cracking Sound?
If crashing, the information you want to post is your journalctl logs, thermal information and a list of any user installed Gnome Shell Extensions.
If Speaker Noise; post your output for your sound card info:
