< /* peam rms level structure like we get from hardware
<
< maybe in future we can memory map it so I just copy it
< to user on ioctl call now an dont change anything
< rms are made out of low and high values
< where (long) ????_rms = (????_rms_l >> 8) + ((????_rms_h &
0xFFFFFF00)<<24)
< (i asume so from the code)
