Raspberry pi 4 | Unable to force sound through jack

Fri Sep 13, 2019 9:35 pm


on one of my raspberry PI 4, I can't get audio through the 3.5mm jack (I don't know if 'm getting any audio through DMI)
I have forced the audio to go through the jack (using raspi-config):

Code: Select all

sudo amixer cset numid=3 
numid=3,iface=MIXER,name='Master Playback Volume'
  ; type=INTEGER,access=rw------,values=1,min=0,max=65536,step=1
  : values=1
I can't get any audio from the usual apps: VLC, Chromium...

Sound works fine from another PI and also when using:

Code: Select all

omxplayer -o local sample.mp3

As I don't hear a thing with:

Code: Select all

omxplayer sample.mp3
this means I can rule out any cable/speaker issue.

I have checked with alsa-mixer, the volume isn't set to 0 (same with the desktop widget).

I have to admit I can't think of anything else.

Run sudo rpi-update; sudo reboot. There's a fix for analog audio in today's update.
