I habe a question regarding the noise cancellation.
Currently my setup looks as follow:
I have an RPi running as an pulseaudio server. Connected to the RPi is the ReSpeaker Mic Array v2.0 via USB and and soundbar over SPDIF.
Now on a server runs mycroft which connects as a client to the RPi pulse server and gives its answer through the speakers (connected to the SPDIF port). Mycroft also gets its Audio / Mic form the pulse server so through the ReSpeaker Mic Array v2.0.
Furthermore another device (squeezebox server) can play music over pulseaudio through the to the soundbar.
Currently I can’t get the noise cancellation working therefore mycroft “hears” also the music while listing for the wake word etc. I don’t want to connect the soundbar via the 3.5mm headphone jacket on the ReSpeaker Mic Array v2.0.
How can I pipe the music to the ReSpeaker Mic Array v2.0 so it know what it needs to cancle out?
