Yet another "can't get sound from RPi 3 audio jack" question

Project help balenaSound
1

Hello, I have just installed Balena Sound on two Raspberry Pi 3, one is a “B+” and the other a “B” and I can’t get audio from the 3.5mm jack on either of them. I have tried disabling multi room, I have added RESIN_HOST_CONFIG_hdmi_ignore_edid_audio = 1, made sure “audio=on” is in Define DT overlays. What else can I do? In alsamixer, when I press F6 to choose a sound card, I only see:
- (default)
0 vc4-hdmi
I tried
amixer cset numid=3 1

too. None of this gets audio from Spotify or Bluetooth, or from speaker-test.
What else can I do?

Here is the output from my config.txt:

root@6c7d300:~# cd /mnt/boot
root@6c7d300:/mnt/boot# cat config.txt
avoid_warnings=1
disable_overscan=1
disable_splash=1
dtoverlay=vc4-kms-v3d
dtparam=audio=on
dtparam=i2c_arm=on
dtparam=spi=on
dtparam=audio=on
gpu_mem=16
hdmi_ignore_edid_audio=1

A bit more info, from the audio terminal:

root@fbb08b215527:/etc# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: vc4hdmi [vc4-hdmi], device 0: MAI PCM vc4-hdmi-hifi-0
Subdevices: 1/1

hi, are you setting a AUDIO_OUPUT variable on the dashboard?

you can check out the documentation here: https://sound.balenalabs.io/docs/customization/

maybe try to explicitly set it to the 3.5mm jack and see if that helps. I worry that it won’t work since your device seems to not detect the onboard audio and only indicates the hdmi port

Yes, I tried AUDIO_OUTPUT = RPI_HEADPHONES and RPI_AUTO.

What version and arch (32bit or 64bit) of balenaOS have you installed on your RPI3 B+ and B?

14

balenaOS 2.47.0+rev1

15

Can you help regarding the second part of the question? balenaOS comes in a 32 and 64 bit flavours for the raspberry pi 3. Check out https://github.com/balenalabs/balena-sound/issues/82

there isn’t a 32bit option available from the drop down on the cloud console. i installed 64bit for raspberry pi 3

21

Oh I see, I have to create another application to use 32bit images… I’ll try that. BRB

22

ok I think you might have created a raspberrypi3-64 type application, which is why the image download is only for that image type. You can try the fix mentioned here: https://github.com/balenalabs/balena-sound/issues/82#issuecomment-607216116

or start over and create a 32bit application…

23

upps, hehe you got it :slight_smile:

ok, that fixed it. the 32 bit version worked “out of the box”.
Thanks everyone!
