Describe the bug

Forwarded from https://bugzilla.redhat.com/show_bug.cgi?id=2121437

The application was open during several hibernations and one sleep of the OS. At some time changing the volume of an application by scrolling on the textfield stopped working. When I tried changing the volume of the application by focusing the textfield and holding the up-key it worked but EasyEffects crashed seconds in the action.

Expected Behavior

changing the volume with scroll should have worked or at least no crash

on_node_info at ../src/pipe_manager.cpp:401

At this line what we do is

if (const auto id = param.id; id == SPA_PARAM_Props || id == SPA_PARAM_EnumFormat || id == SPA_PARAM_Format) {
        pw_node_enum_params((struct pw_node*)nd->proxy, 0, id, 0, -1, nullptr);
}

This is something PipeWire also does in its own code in different places. pw_node_enum_params is a PipeWire function and not something defined in EasyEffects code. I think there is a good chance we crashed because of some bug in PipeWire. But I have no idea about what it could be.
