Did a forum search before posting this and found nothing that addressed the problem so
Desktop an Asus Z97 Intel I7 7700 sound is this according to inxi
Device-1: Intel 200 Series PCH HD Audio driver: snd_hda_intel
Device-2: NVIDIA GM107 High Definition Audio [GeForce 940MX]
Sound Server-1: ALSA v: k5.10.79-1-MANJARO running: yes
Sound Server-2: PipeWire v: 0.3.40 running: yes
I recently changed from Pulse to Pipewire without problems. EasyEffects 6.1.4-1. Audio routing works in Pipewire and sound works well. Easyeffects Spectrum display only shows from 20 Hz to a little less than 10 KHz- The system has audio bandpass all the way to around 20 KHz although it rolls off a few DB around 20 KHz. I am curious about whether there is some configuration that needs to be changed for the complete spectrum to be displayed. Under spectrum settings I have from 20 Hz to 20 KHz to be displayed and 200 points for the display but the display stops just shy of 10KHz. Any suggestions or pointers on where to look or what to do to get full functionality would be appreciated.
