Clarification on Hifiberry Alsaeq guide

I have just got going with the latest Volumio, Hifiberry AMP+ and a Raspberry Pi 3 with WiFi.

I want to add a software equalizer to my setup. Hifiberry's official Alsaeq guide on https://www.hifiberry.com/guides/guide-adding-equalization-using-alsaeq/ looks promising but there are some things that I want to have clarified, as I couldn't hear any difference to the sound:

Where is the asound.conf file in Step 4 supposed to be? In what directory?
If applicable, are the lines in Step 4 supposed to replace an existing asound.conf or to be appended?
Are the lines type hw card 0 and slave.pcm "plughw:0,0"; correct for all Volumio installations? Can the 0 values sometimes be other values?
Does the system need to be rebooted somewhere along the process?
Does changes to the equalizer affect the system real-time?

Thanks for your assistance.

Hi,

the asound.conf is located in /etc

You also need to make sure the palyer application is using the default sound card. You need to check how mpd from Volumio is configured and what sound output it is using.

This guide is provided "as is", we can't guarantee that it will work with a specific distribution.

Best regards,
Daniel
