I have looked at that, but it remains a mystery in some part.  The
async section was as well before it was redone.  I will probably have
to read it several more times and find some concrete examples before
this dim bulb starts to glow.

Thanks.
void pa_state_cb(pa_context *c, void *userdata) {
        pa_context_state_t state;
        int *pa_ready = userdata;

        state = pa_context_get_state(c);
        switch  (state) {
                // There are just here for reference
                case PA_CONTEXT_UNCONNECTED:
                case PA_CONTEXT_CONNECTING:
                case PA_CONTEXT_AUTHORIZING:
                case PA_CONTEXT_SETTING_NAME:
                default:
                        break;
                case PA_CONTEXT_FAILED:
                case PA_CONTEXT_TERMINATED:
                        *pa_ready = 2;
                        break;
                case PA_CONTEXT_READY:
                        *pa_ready = 1;
                        break;
        }
}
