Hi Tim,
thank ou for your reply, I completely agree with you, and I don't really have any explanation. I try a lower Analog gain boost and analog gain, it's better, but still not perfect and it's not what recommend IQaudio.
I try to do some test sound directly with mplayer using only raspbian properly parameterized with alsa at 0 dB and the gain set as defined by IQaudio in the manual, and that works.
Finnaly driving by curiosity I try Volumio, and everything is fine.
I haven't have time to check from where it comes, but too me it could be due to a different version of MPD or ALSA (?).
It's very strange.
When I check with alsamixer it's the same settings but obviously that sound different. (not different in audiophile terms ;-) ) Different such as one is OK and the other one make your ears bleeding due to the distortion.
