[PROBLEM] How to enable Parametric EQ?

[skris88]

Hi.  

I got my moOde audio player working, and working very well!  

I'm using a Pi 4 with 17,000 16/48 files on a USB flash drive.  Audio is through an external USB DAC.

However changing settings on the Parametric EQ did not affect the audio.  

Even a drastic setting like -9dB at a Q of 0.7 (two whole octaves width) at 250Hz did... nothing.

So, thinking it does not work with external audio, I switched to HDMI audio and connected the Pi to my AV receiver, but still no affect to the output (with that same drastic Parametric EQ setting as above).

What am I doing wrong?

Thanks!
