I am going to set up an independent thread for pulseaudio context and the related stream setup and I would like to use "Polled" model instead of "Asynchronous " model to feed the audio raw data .

There is some useful information about thread safety in the docs here:

The short answer is that you must use locks to prevent concurrent calls
to the pulse APIs. It is not safe for two threads to execute calls to
pa_stream_write() simultaneously.
