-31 is the reset value, and means don't apply attenuation
When DialNorm is -30 means the decoder must apply -1 dB of attenuation, and so on until a value of -1 to apply -30 dB of attenuation. When DialNorm is 0 some decoders apply -31 dB of attenuation but others apply -0 dB, then the most reliable value to reset attenuation is -31.

No, dialnorm is just like a volume control for all channels. If it's set to -27dB then it means that all output will be 4dB lower than if it's set to -31dB, assuming the decoder applies the dialnorm values. It doesn't change one channel relative to any other.
As tebasuna51 said, if dialnorm is set to -31dB then the decoder won't attenuate its output, so eac3to is acting correctly here. |
