* tas_volume_table contains lookup values for the volume settings
* for tumbler. This is straight from the programming manual
* for the chip, however, it's zero-sourced for your shopping pleasure
* (meaning, you'll have to compute the difference between the desired
* dB and the index value of the proper setting.
*
* This table should've been replaced by the formula:
* dB = 20 log(x)
* but, since there's no log() or supporting functions like exp(),
* my implementation of the above won't work. Yeah, I could do it
* the hard way, but this table is just easier :-)
*
* For reference, -70 dB = tas_volume_table[0]
