Thanks Colin for your suggestions, that give me some good directions to
start with.
I tried to modify existing module "module-cork-music-on-phone" , I have few
queries:
1. I am now able to Cork(Pause) the "event" stream while a new "phone"
stream arrives. but instead my requirement is to to permanently STOP the
"event" stream
instead of Corking while "phone" call stream exists? Is there any
event/api I can use to achieve this?
(Currently I am corking the stream using pa_sink_input_send_event(ignore,
PA_STREAM_EVENT_REQUEST_CORK, NULL) API )
2. I just need to give a try to play sample cache (beep) first in the same
module (module-cork-music-on-phone)
{Just Playback no role supression initially at this stage} for that:
- How to init the module so that it would load the suppression_sound
(if present) into the sample cache
- Where (Location) to copy the sound (beep) .wav file ?
- How to Play the .wav from the module?
Thanks in advance.

Himanshu Chug
