Is the sound from the hdmi or audio cable?

[DesmondKH]

i tried both and both dont work but the prefferred way would be hdmi

Can you take a screesnshot? The volume sometimes is set to low by default.

Solutions I found:
1.
Use raspi-config command to set the audio output.

According to this there is a known bug if you are using RaspberryPi 4:

for me, i just had to go in raspi-config (sudo raspi-config); then System Options (1 for now), Audio, and option 1 (for audio jack)

Thanks for the extra info. Since there was no reply to this issue I am considering closing it.

I want to play videos from YuoTube, but no sound through HDMI (jack didn't used).

• HDMI attached to hdmi-0 (port next after the power port) on PRi 4 (4 GB)
• uname -a:

  Linux pi-kiosk 6.1.0-rpi7-rpi-v8 #1 SMP PREEMPT Debian 1:6.1.63-1+rpt1 (2023-11-24) aarch64 GNU/Linux

• cat /etc/os-release:

  PRETTY_NAME="Raspbian GNU/Linux 12 (bookworm)"

What I already tried:

1. sudo raspi-config

   • System Options → Audio (set vc4-hdmi-0) + reboot
   • check audio device: alsamixer
     

2. change/add options in /boot/config.txt in all combinations:

   • hdmi_dirve=2
   • dtparam=audio=off (change from dtparam=audio=on)

3. change params in /usr/share/alsa/alsa.conf:

   • defaults.ctl.card 0 to defaults.ctl.card 1
   • defaults.pcm.card 0 to defaults.pcm.card 1

4. check aplay -l after step 3:

All that with no luck — no sound while playing videos :(

Hey, this might be a solution:
#553 (reply in thread)

Also if you tell me it works I can add it and ship it in the next version
