Setup on Respeaker Core v2

[hpposch]

Hello,

i am currently trying to setup the echo canceler on my respeaker core v2.
What i want to achieve is that audio that is played (i use pulseaudio for all audio stuff) get's removed from my microphone automatically.

Is this what this software does?
And if yes, can you please give me a more detailed setup instraction, espacially on how to set this up as a daemon service.
I have seen the section for respeaer under the readme file but i just can't get it working.

Thanks in advane for your help! :)

As respeaker core v2 has two loopback channel (channel 6 / 7), you can try ec_hw.
