Audio does not work after re-imaging/installing voice kit 2 Pi Zero (Original HW)

[lestig]

I have spent a few hours chasing this one without luck, so decided to ask for some guidance...

Problem
'Do not have sound card error message' - after reimaging the SD card and installing with the latest build available.

• I am using the original hardware. AIY voice kit v2.0
• BUILD: (2018-08-03).
• Tried adding a line to the config.txt file 'dtoverlay' below. But it should not apply in my case - either way it did not work

Error/Details

• When running the check audio script I get the following error message (I have a voice bonnet so I don't think the suggestion below applies):

You do not have any sound cards installed. Please check that AIY sound card is
properly connected.
For some Voice HATs (not Voice Bonnets!) you need to add the following line
to /boot/config.txt:
dtoverlay=googlevoicehat-soundcard
To do that simply run from a separate terminal:
echo "dtoverlay=googlevoicehat-soundcard" | sudo tee -a /boot/config.txt
Press Enter to close...

Any help will be appreciated!

@tibre Can you paste the complete error ? And can you also share the output of the command "lsmod".

[lestig]

I made it work in a couple of ways:

1. I installed the 2018-04-13 build and it worked without issues.
2. Installed a fresh copy of raspbian (NOOBS v2_9_0) and followed the HACKING.md instructions. There was a problem with the sound card driver enumeration Index (bcm2835 ALSA was enumerated first, Voicebonnet second). Commented out '#dtparam=audio=on' on /boot/config.txt and that solved it (Dimitry's suggestion)

So I don't know why 2018-08-03 does not work with the kit right off the bat, but thanks for following up.

@tibre Can you paste the complete error ? And can you also share the output of the command "lsmod".

Well, with #2 above (Fresh copy of rasbian and following HACKING) I am able to test speaker and record but when trying the assistant_grpc_demo I get an error message:

Failed to import google.cloud.speech. Try:
env/bin/pip install -r requirements.txt

I am not running a virtual environment. Also, just replying to your previous ask here the lsmod output of my current configuration:

@tibre Can you please confirm that you used 2018-08-03 image with the VisionBonnet (v2.0) and sound check failed with You do not have any sound cards installed message right after the boot? It's pretty weird, especially if the same sound check works fine with 2018-04-13 build.

Can you please also attach the output of dmesg command right after the check fails?

[lestig]

@dmitriykovalev Yes, that's the file:

MD5
MD5 hash of aiyprojects-2018-08-03.img.xz:
386dafcc76c8539990e75e374f33b513
CertUtil: -hashfile command completed successfully.

VoiceBonnet (v2.0) not VisionBonnet

I will reimage an SD with that build and will give you details. Now, the only difference that I recall and that might be creating the problem is updates. When installing 08-03, updates are an option and they are executed right away compared to 04-13.

[dmitriykovalev]

@tibre Sorry, right, that was a typo, VoiceBonnet :) Please do not install any updates for now (we are working to fix this) That could be exactly the source of problems.

[lestig]

@dmitriykovalev Thanks for the update.
That said, any ideas.suggestions how to move forward pass this message (when trying latest Noobe's install+HACKING instructions):

Failed to import google.cloud.speech. Try:
env/bin/pip install -r requirements.txt

[dmitriykovalev]

@tibre That's weird, how do you run cloud speech example, what's the command line? This error message is obsolete but still shouldn't happen. Are you using python3?

[lestig]

@dmitriykovalev It seemed odd to me as well. Yes, I am executing using python3 as usual. To recap:

1. Installed latest Rasbian build (Noobe 2.9.0)
2. Followed Hacking.md instructions (Had a problem as bcm2835 ALSA drivers where enumerated 1st)_
3. Ensured only voicebonnet is enumerated and active - _commmented out 'dtparam=audio... _
4. Confirmed everything is functioning properly. Can access sound card, record, play without issues...
5. Ran assistant_grpc_demo script and got that error message...

_I tried a number of things to no avail. I even bypassed the call in the speech script (if I remember correctly...) but that created other issues.

[dmitriykovalev]

@tibre Have you installed https://pypi.org/project/google-cloud-speech/ library?

sudo pip3 install google-cloud-speech

[andrewtvuong]

I've noticed certain programs no longer produce sound from 4-13-18 to 8-3-18. I'm not certain but it seems the culprit has something to do with switching to PulseAudio from ALSA? I don't know much about the subject.

[andrewtvuong]

@tibre Have you installed https://pypi.org/project/google-cloud-speech/ library?

sudo pip3 install google-cloud-speech

wow that's awesome! I'm new to the subject, but is there a way to have its model so I can run on device? like a small subset that recognizes common commands.

[dmitriykovalev]

@andrewtvuong Yes, we switched to PulseAudio (it still uses ALSA underneath). Which programs don't work for you?

[andrewtvuong]

@dmitriykovalev Not part of AIY or Rasbian images:

Raspotify - https://github.com/dtcooper/raspotify
built from Librespot library for https://github.com/librespot-org/librespot

[mdbrewer]

I am having the same issue with two out of the box AIY kits, using the 2018-11-16 build.

You do not have any sound cards installed. Please check that AIY sound card is
properly connected.

For some Voice HATs (not Voice Bonnets!) you need to add the following line
to /boot/config.txt:

dtoverlay=googlevoicehat-soundcard

To do that simply run from a separate terminal:

echo "dtoverlay=googlevoicehat-soundcard" | sudo tee -a /boot/config.txt
Press Enter to close...

I have updated the firmware, APT-upgrade, and checked the help forum. Still no go.

[mdbrewer]

I loaded AIY Kits Release 2018-04-13 and things work. I am not sure the difference.

[NuclearMonster]

I have this "You do not have any sound cards installed." issue as well with the check_audio script on the v2 pi zero kit

[nathanjnorris]

Hi, I'm having the same issues as everyone else. I have the AIY Voice Kit 2.0 and when I run cat /etc/aiyprojects.info this is the output:

Any help with this bug would be much appreciated :)

Hi,

I think that the cause is that the driver disappears by updating firmware.
Try the following commands.

cd /usr/src
sudo dkms install aiy-1.1
sudo dkms install aiy-vision-1.1
sudo dkms install aiy-voicebonnet-soundcard-1.0
sudo dkms install leds-ktd202x-1.1
sudo dkms install pwm-soft-1.1
sudo reboot

The name of the driver changes depending on the AIY Kits OS version, check with 'ls /usr/src'

[NuclearMonster]

sudo dkms install aiy-voicebonnet-soundcard-1.0

thanks, this one did it for my project, once I made it 1.1 sound worked again. Oddly, all the other modules that were useful for the voice kit were already installed!

Hi @mongonta0716 , thanks for sharing.

Error! DKMS tree already contains: aiy-voicebonnet-soundcard-1.0
You cannot add the same module/version combo more than once.

I'm getting this message for every command you listed. Should I uninstall and reinstall? If so I'm not familiar and don't want to mess up dependencies or some kind of problem, would it be safe to uninstall and how? rm -rf?

[mongonta0716]

Hi @andrewtvuong

Sorry I couldn't help you.
If there is a driver it is a different case from me.I have written something unrelated to this Issue.In my case,the following command was executed and the driver was built.
sudo dkms install aiy-voicebonnet-soundcard-1.0

My environment
Google AIY Voice Kit V2
BUILD: 2018-11-16 and apt-upgrade
firmware:4.14.79+

After a fresh install of 11-16 image, an update, then running the above driver installs, and it works.

This solved for me. Thanks

[jreyn88]

Why would an image created by starting with AIY Voice then adding Shairport-Sync and Homebridge with V2 voicebonnet, work in another 3b but not the Zero WH that came with the voicebonnet? I tried the above steps but it recognizes a Google soundcard in the Zero instead of the voicebonnet in both 3b's.

[andrewtvuong]

@jreyn88 Very strange, but I had a lot of problems on 3A+, that resolved itself after several reimages. Keep downloading and changing SD cards, update etcher. I don’t understand the reasons, but all my problems are gone.

[juanfonsecasolis]

I downloaded the 2018-08-03 build and ended up repeating timbre's experience. Could you remove that build to avoid that other people experience the same problems, please?

[trixter13]

I am having this same issue on the 2019-11-13 build, should I just flash the older version?

Edit: Nevermind.. I had to reboot after adding dtoverlay=googlevoicehat-soundcard to the config. It works now.

[rudjer]

I'm having this same issue on a V2 voice bonnet with the 2019-11-13 build running:
~/AIY-projects-python/checkpoints $ python3 check_audio.py
I tried adding to /boot/config.txt and rebooting, but that didn't help, perhaps not
surprisingly given that the message only implies this might help for V1.

This seems to have been a update issue. I reinstalled a fresh flash of the 2019-11-13
build, and skipped the update step of the installation, and now assistant and other
sound card issues are resolved.

Hi, I have a problem with audio, after intalling aiy-2019-11-13.img.xz on the raspberrypi the icon for the speaker on the navigation bar dissaperas, also I have that same message (you so not have any sound card installed. Please check that AIY sound card is properly connected.

I wanted to use the speakers of a samsung TV, but it didnt work, so I connected a speaker in the AUX and it still doesnt work when I check the audio. Help please!

[diegoshh]

by the way Im using a raspberry pi 4
