Cool, thanks.

For simplicity, I think we should probably stick with calling it "volume". I think that the behaviour will be what most people expect. It also avoids the international spelling issue😁

I'm not sure that volume level 8 is the right solution. I think that just tapping off the audio after the AGC without adding any extra gain or attenuation would be preferable. The "half way" AGC is conservative, but the AGC does handle overshoot/saturation gracefully and the difference in perceived loudness isn't that great. If we did want to get closer to a full scale signal, it would be better to increase the AGC setpoint.
