This does rather depend on what the firmware does and why it needs to be reloaded - it is very rare that one can just blindly reload the firmware and frequently changing the firmware will affect the set of user tunable features that can be offered to the application layer. Joining everything up in a way that avoids fragility typically means that the driver will end up initiating all the requests based on higher level requests from audio applications. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
