Sorry for hijacking this thread.
My problem is the same as decribed below.
I’m using AMP+ Card and no Equalizer is working.
In advanced setting soundcard is set to “”sysdefault – snd_rpi_hifiberry_amp, Default Audio Device, sndrpihifiberry”.
If I set this to “plugequal – Equalizer for plughw:0,0” no sound is hearable anymore.
What do I have to do for make Equalizer working with HiFiBerry AMP+?
