Can't get it to work

[Andys280]

Hello . On a raspberry pi zero with freshly installed raspbian I clone the code, everything works ok in the installation, without errors. I answer the questions asked with the default answers and I receive the message that the installation completed successfully. I connected a switch to the gpio pin, but when I press it, nothing happens. I tried to run the command aplay -l . My audio card on the usb port is the second one listed, so I changed the aplay configuration, which for me can be found at the address /user/share/alsa/alsa.conf (at the addresses indicated in the guide, I do not find any files).

admin@Guestbook:~/rotary-phone-audio-guestbook $ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: vc4hdmi [vc4-hdmi], device 0: MAI PCM i2s-hifi-0 [MAI PCM i2s-hifi-0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: Device [USB Audio Device], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

I run the command sudo nano /usr/share/alsa/alsa.conf and change the number from 0 to 1 on the following lines

defaults.pcm.card X
defaults.ctl.card X

Now i run the command sudo /etc/init.d/alsa-utils restart but again, nothing works.

This is what the log command shows me

admin@Guestbook:~/rotary-phone-audio-guestbook $ journalctl -u audioGuestBook -f

Maybe try to install pip install -- user pyaudio

Maybe try to install pip install -- user pyaudio

Can't run your command

admin@Guestbook:~ $ pip install -- user pyaudio
Looking in indexes: https://pypi.org/simple, https://www.piwheels.org/simple
ERROR: Could not find a version that satisfies the requirement user
ERROR: No matching distribution found for user

Tried to change command from --user to --admin , no luck

[s3b3n]

Sry i had an error in the Syntax Try pip install --user pyaudio

I ve installed multiple things and now it starts without errrors , but not working. i can t hear anything in the speakers and no recording is made. i ve even placed an "voicemaile.wav" file in sounds folder. Tested sound card with aplay commands ad works . What can be the problem now ?

[s3b3n]

What is the output from journalctl -u audioGuestBook -f

[nickpourazima]

Hey @s3b3n & @Andys280,

I've refactored and deployed a full rpi img with everything set up and tested as functional on my rotary phone. I used git lfs to upload the .img.gz file so you'll need to install git lfs if you don't already have it and then after a git checkout dev and git pull do a git lfs pull.

Can you please flash the rpi img on your rpi? If you are using the Raspberry Pi Imager you can select it as a custom .img:

username: admin password: password

and set up your wifi network accordingly

Once you've flashed the custom .img and have booted it up you can edit the config.yaml and .asoundrc files as necessary per my updated setup instructions.

Let me know how it goes, thanks!

@nickpourazima

For me it works flawlessly, thank you for the great work. One thing i personally would like to have is the option to configure the volume from every wav seperatly via config.yaml

So everyone can fine tune how loud the beep or the voicemai is.

Great work, i will buy you a coffe for this ;)

[nickpourazima]

Thanks @s3b3n! Glad it worked for you!

I can modify the scripts to accommodate volume levels per wav file. I'll probably call amixer prior to aplay with whatever is specified in the config.yaml. I'll track this new feature in a separate branch and keep you posted.

okay new problem here:

After reboot there is an aplay error: Mar 10 17:48:15 raspberrypi python3[558]: aplay: main:830: audio open error: No such file or directory Mar 10 17:48:15 raspberrypi python3[507]: ERROR:audioInterface:Error playing voicemail.wav: Command '['aplay', '/home/admin/rotary-phone-audio-guestbook/src/../sounds/voicemail.wav']' returned non-zero exit status 1. Mar 10 17:48:16 raspberrypi python3[559]: aplay: main:830: audio open error: No such file or directory Mar 10 17:48:16 raspberrypi python3[507]: ERROR:audioInterface:Error playing beep.wav: Command '['aplay', '/home/admin/rotary-phone-audio-guestbook/src/../sounds/beep.wav']' returned non-zero exit status 1. Mar 10 17:48:16 raspberrypi python3[507]: INFO:main:Recording started...

It seems that after a reboot the directory is wrong ....

i have no clue how this happened

[s3b3n]

Okay my fault i switched the power plug and the usb soundcard ports, the soundcard wasnt recognized, after switching erverything works for me
