Bad quality sound on MoodeAudio 6.x

[Tim Curtis]

Looks normal to me. Both alsamixer and amixer both report the same gain of -15.5dB for the devices main volume control named "Digital". The Analog volume and Analog Boost or whatever its called are not really relevent. They are just two tweaking volumes on the analog side of the PCM5XXX chip.

Since I'm unable to reproduce the distortion you are experiencing there is not much more I can do.
