no sound on jack

[Moule0169]

Hello, I am a new user of Balena Sound, which I have just installed on a Raspberry Pi 4B. OS 2.95.8 Supervisor 12.1.38

The services are active (except the hostname), I can connect via spotify, but I have sound only on the HDMI0 port, not on the 3.5mm jack, nor on the HDMI1. I was in version 3.8.5, I tried to upgrade to 3.8.4 because I saw that a bug had been solved this way in February. I also forced the AUDIO_OUTPUT variable to RPI_HEADPHONES, but it doesn't change anything, the sound is still coming out of the HDMI0 plug.

Can anyone help me? Thank you,

I have a similar problem on my Raspberry Pi 4. I can't get any audio from the 3.5mm jack, haven't checked HDMI yet.

I looked into the logs and found this when starting: audio E: [pulseaudio] module-alsa-card.c: Failed to find a working profile.

It seems to try different profiles but none seem to work: audio E: [pulseaudio] module-alsa-card.c: Failed to find a working profile. audio E: [pulseaudio] module.c: Failed to load module "module-alsa-card" (argument: "device_id="0" name="platform-fef00700.hdmi" card_name="alsa_card.platform-fef00700.hdmi" namereg_fail=false tsched=yes fixed_latency_range=no ignore_dB=no deferred_volume=yes use_ucm=yes avoid_resampling=yes card_properties="module-udev-detect.discovered=1""): initialization failed. audio E: [pulseaudio] module-alsa-card.c: Failed to find a working profile. audio E: [pulseaudio] module.c: Failed to load module "module-alsa-card" (argument: "device_id="1" name="platform-fef05700.hdmi" card_name="alsa_card.platform-fef05700.hdmi" namereg_fail=false tsched=yes fixed_latency_range=no ignore_dB=no deferred_volume=yes use_ucm=yes avoid_resampling=yes card_properties="module-udev-detect.discovered=1""): initialization failed.

What I tried so far:

• force AUDIO_OUTPUT to RPI_HEADPHONES
• disable multiroom by setting SOUND_MODULE to STANDALONE
• check if "audio=on" is set in DT parameters

I am also having this issue. I've been looking through the issues tab and the belena forums and I cant find a response for this question. If I find one I will link it here.

I was having a similar issue, but have audio working after making some changes. I selected my Raspberry Pi device from the balena cloud dashboard and made the following changes:

---

Device variables:

Name	Value
AUDIO_OUTPUT	RPI_HEADPHONES
SOUND_VOLUME	100

Device configuration:

Delete the vc4-kms-v3d entry from "Define DT overlays".

(Found in this thread.)

---

After a reboot, I had working Spotify and Bluetooth audio. I hope this also works for your devices! 😀

@Blazin64 Thank you, deleting that entry actually worked! My sound is working now.

Thank you Blazin64! Your solution also worked for me.

Doing this on my Pi4 makes it spam some errors and using this "vc4-kms-v3d-pi4" fixes it.
