Hi Tanu, Also which thread does all of the hooks (PA_COE_HOOK_SINK_INPUT_PUT, and so on) run in? My understanding is that within the PA daemon process, PA daemon has a mainloop (which is a thread), and IO threads within the sinks or sources. Are there threads corresponding to each of the client applications (paplayer and so on)? Thank you every much.

What about a sink_input disappears during that loop? Is?apply_cork_to_sink()??running in the PA daemon's mainloop? And all sink_input's come and go only happen in the PA daemon's mainloop as well? Many thanks.
