You could try to watch for cdev events (i.e. creation of daX device nodes) instead
of driver events. But I am not sure if cdev events are in 7.1, they are definitely
in 7.2:

notify 1000 {
        match   "system"                "DEVFS";
        match   "subsystem"             "CDEV";
        match   "type"                  "CREATE";
        match   "cdev"                  "^da[0-9]+$";
        action  "echo 't120o3l32 b>c+f+16' > /dev/speaker";
};
