Jack source removed for no reason

Hello everyone,

I've created a jack source and a jack sink a month ago on a Linux Debian 12 machine (PulseAudio version is 14.2) with the following commands:

pactl load-module module-jack-sink sink_name=raw_device_out client_name=raw_device_out
pactl load-module module-jack-source source_name=raw_device_in client_name=raw_device_in

The jack source (raw_device_in) creation was confirmed at the time because it was found in the output of the following command:
pactl list sinks

A month later, without modifying the machine or restarting it, the same command

pactl list sinks
no longer displays this jack source raw_device_in in its output. The sink raw_device_out, however, is still present when i run

pactl list sources
The PulseAudio logs do not mention any problems.

The problem may be more with jack module than with PulseAudio, but just in case I'm asking: does anyone know if a source can be automatically deleted by PulseAudio ?

Feel free to ask any additional information.
Thank you and have a nice day !

Julien
