The driver and the Family are jointly responsible for maintaining the
format. The HAL uses what it finds in the IORegistry. Further, the HAL
won't change anything until the format change or major engine change
notifications are received.

Which part of the Audio Family chain is responsible for maintaining the
exclusivity of a format? Is it the driver or is this handled further
up the
chain? In other words, if I have a device that supports multiple
formats
and a client is currently using one format, but another client
requests a
different format, does returning an error from performformatchange in
my
core audio driver keep the second clients request from being fulfilled
or
does it even make it this far in the Audio Family?
Thanks,
