Not sure which post you are asking about.
What I meant was, from a terminal window, and from the command line, you can use the following command to scale the DAC chip output down, -6db. The first line above was the command:
amixer sset Analogue 0
The next few lines were the output.
I think dunghnguyen was giving you another method, using alsamixer. May be easier (?) not sure.
In either case the result is the same, you scale the output down by half.
Beyond that, Frank would have to tell us if the max limit is the same for DAC+ and AMP+, or different.
