Hi,
i’d like to see a volumio gui option to select the DSP mode utilized by the PCM5122 DAC chip and I strongly suggest setting the standard mode to
Ringing less Low Latency FIRDSP program measurements & test here:
Archimago: MEASUREMENTS: HiFiBerry DAC+ Pro, PCM5122 digital filters & further thoughts on filtering…
and found it to be sounding best of all four available DSP modes.
you can currently change your DSP program by running alsamixer, to make changes permanent use
sudo alsactl store
and to reload the settings upon boot add a line to your /etc/rc.local:
sudo alsactl restoreright before your
exit 0
line.
Kind regards
Matthias
