it would be feasible only if we have a certain daemon. otherwise, i don't think its a good style to invoke a user-space tool from the kernel driver. > * initiated by the user, through the configuration GUI. or: more clever hotplug scripts. basically, the whole initialization stuff for such dynamic devices is the job of hotplug manager. so, we can provide a proper init/delete script for each card. e.g. loading the firmware, then set up the default or restore the last status. but yes, for this way, it would be nice to have a "state", so that alsactl can know whether the data to restore matches with the current state. in this way, the unmatching data can be ignored by the first call of alsactl in the init script.
