Roon Bridge and ALSA

Hello, not sure this is relevant to the current discussion, but I am trying to implement eq using LADSPA plugins. Does RoonBridge use the alsa control settings defined in asound.conf?

I have setup ladspa dsp plugins as described here:

When testing it using aplay command line, the dsp configuration works. But not with roon. Would it be required to setup a virtual sound card ? Any hints would be appreciated

EDIT: this topic describes using BruteFIR using loopback device : [Guide] High quality room correction with Raspberry Pi & Roon It is possible to do something similar but without BruteFIR ?

This topic can be closed as 1.3 will provide parametric EQ.
