The minimum value is unchanged so that the default 0dB has the same integer control value. The original maximum of 400 (+100dB) was the largest value that can be mathematically handled by the DSP. The actual maximum amplification is +12dB. Backport Note: Identical to upstream commit. This was originally thought to be only a cosmetic issue (the user can simply reduce the volume) but for some complex audio topologies with SOF Audio DSP + CS42L43 + multiple CS35L56 it has turned out to be not obvious to the user what the problem actually is and what to do to fix it. As support for these topologies went into 6.10 we would like this commit to be backported into 6.10.
