Bad quality sound on MoodeAudio 6.x

With MPD volume control set to Software, knob in GUI set to 100%, and Max ALSA volume set to 85% from settings menu, I can observe the following:

Code:
#amixer output

Simple mixer control 'Analogue',0
  Capabilities: pvolume
  Playback channels: Front Left - Front Right
  Limits: Playback 0 - 1
  Mono:
  Front Left: Playback 1 [100%] [0.00dB]
  Front Right: Playback 1 [100%] [0.00dB]

Simple mixer control 'Digital',0
 Capabilities: pvolume pswitch
 Playback channels: Front Left - Front Right
 Limits: Playback 0 - 207
 Mono:
 Front Left: Playback 176 [85%] [-15.50dB] [on]
 Front Right: Playback 176 [85%] [-15.50dB] [on]

Alsamixer reports 100<>100 for Analog (0dB), and 55<>55 (-15.5dB) for Digital. When I try to move the Analog slider in alsamixer, it moves between 100 and 0 (0 dB or -6 dB, only two possible positions).

               

So, I don't see the GUI knob's volume anywhere, but it actually does controls the volume, and as I said before, it really clears up the distortion, while the ALSA setting - doesn't.

With MPD volume control set to Disabled, I get absolutely same results, it is just that the knob is now gone from GUI, hence no way to remove distortion.

Hope, this helps.

[UPDATE] The knob volume can be checked and set by mpc command:

Code:
$ mpc
volume:100%   repeat: off   random: off   single: off   consume: off


I can control it via command line as well as from GUI

Code:
$ mpc volume 70
volume: 70%   repeat: off   random: off   single: off   consume: off


If I set the MPD volume control set to Disabled, then the mpс volume is n/a

Code:
$ mpc
volume: n/a   repeat: off   random: off   single: off   consume: off

And finally, with MPD volume control set to Hardware, I can control the volume via mpc, and GUI, but as you said, it effectively controls the ALSA volume (digital).
