We use TAS2557 + LEARNING BOARD + PPC3,want to see realtime sep & stp.
in PPC3 rule,we need go to the Turning and Audio Processing page at first.
but in this page,amplifier volume force to -10dB(if use 4Ohmn speaker ,output power=1W)
Even if we increase the input volume stream over than -10dB, the volume will remain at -10dB
Down picture is behavior
In conclusion ,how can we up the volume to 0dB ?
