Looking for help fixing this issue

Which audio board do you use, Voice Hat (for Pi 3) or Voice Bonnet (for Pi Zero)?

Can you please verify that you are using the latest SD card image from our website? If you are still having this issue, can you manually type sudo dtoverlay googlevoicehat-soundcard in the terminal and then run check audio script again?

I had the same issue with a newly installed image.
Running this sudo dtoverlay googlevoicehat-soundcard worked for me.

[dmitriykovalev]

@IchordeDionysos Perfect! You can put dtoverlay=googlevoicehat-soundcard string into the /boot/config.txt file to load overlay on every Pi boot. We'll try to figure out how to improve our SD-card image.

@voicehat Did this help to solve your problem?

hi, @dmitriykovalev
i have the same problem,
i wrote the command : sudo dtoverlay googlevoicehat-soundcard
and it work only once, I retried after I reboot of the raspberry pi and it doesn't work anymore,
the terminal show this :
Traceback (most recent call last): File "/home/pi/AIY-projects-python/checkpoints/check_audio.py", line 172, in <module> main() File "/home/pi/AIY-projects-python/checkpoints/check_audio.py", line 167, in main do_checks() File "/home/pi/AIY-projects-python/checkpoints/check_audio.py", line 129, in do_checks if not check_voicehat_present(): File "/home/pi/AIY-projects-python/checkpoints/check_audio.py", line 75, in check_voicehat_present return any(card_id in card for card in get_sound_cards().values()) File "/home/pi/AIY-projects-python/checkpoints/check_audio.py", line 50, in get_sound_cards with open(CARDS_PATH) as f: # pylint: disable=invalid-name FileNotFoundError: [Errno 2] No such file or directory: '/proc/asound/cards' Press Enter to close...
thank you
ps: i tried to type the command in the /boot/config.txt, but i don't have the permission and i tried to add the permission in the properties of the file but I'm not allowed to do that too

@blandiant

That's pretty weird, sudo dtoverlay googlevoicehat-soundcard should always work. You have to run it every time after reboot. Another way is to edit /boot/config.txt and insert (slightly different!) command dtoverlay=googlevoicehat-soundcard which does the same on every boot automatically. You need to use sudo in order to edit /boot/config.txt file. More info about this configuration file and how to edit it — https://elinux.org/R-Pi_configuration_file

Typing dtoverlay=googlevoicehat-soundcard into / boot/ config.txt worked
for me too.

I think I used *sudo nano /boot/config.txt *to make the edit.

Thanks.

Thank you a lot, it works now,
I only have a small problem, when i use the "check audio", i say "1 2 3 testing" the sound volume of the recorded audio is low, even when i speak very close to the microphones
And when I use the assistant example I have to say "ok google" really close to the microphones to activate the assistant, otherwise it doesn't work
Do I open an new issue ?
Thank you again

@blandiant Since the volume issue was mentioned in the comments of #307 as well, I've filed #356 to track it.

[dmitriykovalev]

Alright, let's close this one and switch to #356.
