ETO once started testing the output levels (to be fair, with a multimeter only) and it was very close to the theoretical value based on the data sheet and how the CPC mixes the channels.See [https://www.cpcwiki.eu/forum/technical-support/amstrad-cpc-volume-decibel-table/ Discussion on the forum]

See Volume 0 is indeed silent. It is not just logarithmic attenuation where maximum attenuation of a channel is just very quiet and not silent.
