While pulseaudio should never crash, this crash happens when the daemon is shutting down, so the crash isn't your biggest problem. In order to debug the crash, a backtrace is needed. If you want to provide that, here are some instructions: https://wiki.freedesktop.org/www/Software/PulseAudio/Documentation/User/Community/ > I attach the log. > I don't see an clear cause for this. Please, would you help me to > investigate further about this behavior? It looks like you switch from HSP to the A2DP source profile. The A2DP source profile doesn't have a sink associated with it, and no other sinks exist either, so that's why the null sink gets loaded. It's module-always-sink that ensures that there's always at least one sink in the system. Pulseaudio shuts down, because there are no clients. The automatic shutdown is normally prevented by module-systemd-login, which keeps pulseaudio running as long as you're logged in, but apparently you don't have any login sessions active (maybe you logged in via ssh - I'm not sure, but ssh might not register a login session in systemd- logind). You can put "exit-idle-time = -1" to /etc/pulse/daemon.conf to disable the automatic shutdown. -- Tanu
