I recommend that you be explicit about your source references.  If this struct owns the source, have it maintain a strong reference to the source.  In your case it seems that `fd` is an attribute of the struct, so you could create the source when the struct is initialised with `fd`.  You don’t have to configure or resume it at that point, just create it.
