[pulseaudio-discuss] dynamic routing through pulse audio

[Himanshu Chug]

Thanks Colin. got your point here.
Now similar to music cork over phone, I need to cork the stream with
role="event" when another stream with role="phone" becomes active.
(here event can be sms alert etc)  , Do I need to write any new module for
this? or this can be achieved some how, any pointers can be helpful?

Best Regards,
Himanshu
