One of the ways to use the DOE: Sound is to NOT pump the sound down your VoIP app but instead for everyone to have their own copy of the sound app (Syrinscape in this case). This way there is way less bandwidth being consumed and there is less setup for whoever would be originally running the audio app and pumping the sound down the VoIP app (and that doesn't have to be the GM but can be anybody!).
This IS all spelt out in the Manual and on the Wiki Page, btw ;)
Cheers
