The problem is that this also happens when it's not
required, and that the change is permanent.

Just imagine: someone at the other end of the building,
or at the other end of Parma, accidentally disconnects
the MADI signal I'm receiving from him for a second.
The driver / card switches to its internal clock and
does not switch back when the signal is restored. So
it is now permanently misconfigured. And before you 
say I'm dreaming: we *do* have optical links running
all over the town, they *can* carry a MADI signal and
they *will* be used to do that.

Do you really expect me or someone else to sit watching
your control panel all day ? Do you have another solution
than an application watching the state of the card, and
restoring it when necessary ?

I have already told you twice before, and a third time
above. So I'm not going to repeat this again. If you
don't want to understand, which seems to be the case,
I'm wasting my time. I *do* understand your arguments,
but they just don't apply in this case - I'm not writing
a desktop MP3 player.
