So, this is more of a Pulse question.
We know even dormant streams are sufficient to keep the audio card from
suspending.
I don't know if dormant streams have mixing overhead or impact the
volume algorithms being used.

So, I'm happy to implement if it's going to make a significant
difference.
But if it's really true that dormant streams don't hurt, this probably
doesn't negatively impact things.
