Agreed.  The changes of those names during operation is fairly
intrusive, and can bring many side-effects.

Any reason that mixername and co have to be changeable inevitably?
If that's about UCM profile and its selection of the hardware
configuration, can it be another additional information instead of
overwriting the existing strings set by the driver?


thanks,

Takashi
