Looks pretty much like what I have (RPi3, HFB DAC+ Pro) and I’ve not touched any of the odder settings. Mine sounds just lovely; if it works…

Hi antac,

I’ve tried your settings and I still have a big problem, Same version of Volumio, same DAC, RPI3.
Most songs (mp3 format) vocals are very low or unhearable over instruments or when i can hear them on some songs the vocals sound like “real audio” in in 1997 over dial up modem, really that bad.
Same music files sound fine on my old sound blaster 5.1 live on my desktop and also sounds much better through the RPI3 audio jack. It’s not the cable or the speakers tried a few.

I think I got ripped off by Hifiberry.

HFB are really rather good with support and will help if they can. Get in touch with them and see what they suggest…

Hello,
Sorry, I got a question, why do you use DSD over PCM?
This Pulse Code Modulation PCM degrades the DSD signal by re-modulation.
Is there a reason for doing so :question:
The volume can also be controlled with DSD Direct.

Playback options:
DSD Direct : On
Automatic volume level for DSD : ON
Volume Normalization : off
Buffer Size : 2MB
Buffer before playback : 30%
Persistenrt Queue : On

Excellent sound with this setting
