Thanks for helping a (Raspberry) noob here hehe.

I got a different result:

$ arecord --list-devices
**** List of CAPTURE Hardware Devices ****
card 0: sndrpigooglevoi [snd_rpi_googlevoicehat_soundcar], device 0: Google voiceHAT SoundCard HiFi voicehat-hifi-0 []
  Subdevices: 0/1
  Subdevice #0: subdevice #0

Therefore would my recording device still be hw:0,0?

aplay gave me this:

aplay --list-devices
**** List of PLAYBACK Hardware Devices ****
card 0: sndrpigooglevoi [snd_rpi_googlevoicehat_soundcar], device 0: Google voiceHAT SoundCard HiFi voicehat-hifi-0 []
  Subdevices: 0/1
  Subdevice #0: subdevice #0

I believe it’s the same ID like above right?

@cr4z33 Details are dependent with also your asound config. But,
Can you record and play some audio in Terminal?

arecord -t 5 test.wav & aplay test.wav

Can you execute this? tell me the result.

(I haven’t had voiceHAT, so cannot guaranteed, but same name could be available.)

I get an error and please note that I’ve tried to translate to English. :winking_face:

arecord -t 5 test.wav & aplay test.wav

Try this.

arecord -t 5 -D hw:0,0 test.wav

Does this make test.wav?
If so, try this again.

aplay -D hw:0,0 test.wav

@sean
Nope. :pensive_face:

arecord -t 5 -D hw:0,0 test.wav
arecord: main:574: unrecognized file format 5

@cr4z33

cat ~/.asoundrc

Tell me the result.

How you can setup previously? (I think you purchased that device for Google AIY project. Was there any instructions?)

@cr4z33
Oops ! my mistake!

arecord -d 5 -D hw:0,0 test.wav

pi@raspberrypi:~ $ cat ~/.asoundrc

It’s the so- called Google Voice Kit AIY (https://aiyprojects.withgoogle.com/voice-v1/).

I used a ready meal Raspbian image made by Google.
Apart from creating the JSON file everything else consists of ready scripts (i.e assistant_library_demo.py is a script to runs and uses Google Assistant):

Hmmm… As I know,

arecord -d 5 test.wav
aplay test.wav

This should work because there is no other suspicious things. your card and device no is 0,0 and that is the default.

Again I made a noob error… I ran both commands at once lol! :smiling_face_with_open_mouth_cold_sweat:

Running them separately worked like a charm! :thumbs_up_medium-light_skin_tone:

I am going now to retry with the module addition.
