Google Assistant is not responding to voice input

[drkostas]

Hi @shivasiddharth ! I successfully finished the installation of the project on my RaspberryPi 3 for the Google Assistant only, and the assistant doesn't respond to my voice.

• I configured it to use USB input (from USB headphones) and Jack output (speakers). When I am running audio-test.sh it finishes with no problems (I hear the sound on the speakers and the recording is played back to me correctly).
  I only get this warning: Warning: rate is not accurate (requested = 16000Hz, got = 48000Hz) please, try the plug plugin

• The outputs of /etc/asound.conf and ~/.asoundrc are the same:

  pcm.dsnooper {
      type dsnoop
      ipc_key 816357492
      ipc_key_add_uid 0
      ipc_perm 0666
      slave {
          pcm "hw:1,0"
          channels 1
      }
  }
  
  pcm.!default {
          type asym
          playback.pcm {
                  type plug
                  slave.pcm "hw:0,0"
          }
          capture.pcm {
                  type plug
                  slave.pcm "dsnooper"
          }
  }
  

• The outputs of aplay, arecord and cat /proc/asound/cards are the following:

  $ aplay -l

Can you help me identify the issue? Thanks in advance!

If you are on the Dec release, try the following:

sudo nano /etc/pulse/client.conf.d/00-disable-autospawn.conf

Comment the autospawn (add a # infront of the autospawn line).

Restart and see.
