Right, but it's not like none of that wasn't already covered by the many existing CODECs in that space that already paid back their development costs years ago, it's surprising that anyone would try to make something new there. > > > During which time period is the digital mute enabled?

So it really would be the last callback made (with mute = off) to the > codec driver once everything else has been set up then? That's the idea.
