I have a RP 4 and I am trying to get sound out of the minijack socket.. The GUI loudpseaker icon offers analog & HDMI. When I select Analog or HDMI, push the volume to max and close the tab, the loudspeaker icon drops to 0 automatically.

I have tried forcing the analog channel

sudo amixer cset numid=3 1

I have fiddled with all I can using the command alsamixer

But whenever I quit out, the channels zero out. I have tried the le above with the Alsamixer gui.

In :

sudo raspi-config

I have set the advance / audio settings to analog.

sudo raspi-config
[sudo] password for admin:
numid=3,iface=MIXER,name='Master Playback Volume'
; type=INTEGER,access=rw------,values=2,min=0,max=65536,step=1
: values=1,1

But still no sound.

My sound card is:

/proc/asound/cards
bcm2835_alsa

Any ideas would be most grateful. Thank you

    Analog sound works on a vanilla Raspbian. I suggest you start with a fresh install and get the sound working there. Then you can investigate what changes to the system break the sound functionality. – Dmitry Grigoryev Feb 28 at 8:56

You can set the cards by configuring /usr/share/alsa/alsa.conf. Therefore, change it according to the value below.

From:

defaults.ctl.card 0
defaults.pcm.card 0  

To:

defaults.ctl.card 1
defaults.pcm.card 1

  • Thank you for the config change. Sadly it has not made the sound come out of the Jack socket. I am starting to wonder if there is not a physical fault. I can't think of a way to check physical integrity. – Christopher Lowden Feb 28 at 13:02

I checked the hdmi audio output, using

defaults.ctl.card 0
defaults.pcm.card 0 

and it works. I presume this leaves me to deduce that analog circuit is defective. Not really sure what I can do.

  • Please accept your own answer with a click on the tick on its left side. Only this will finish the question and it will not pop up again year for year. – Ingo Mar 3 at 19:33
  • I have rolled back to defaults.ctl.card 0 defaults.pcm.card 0 and bought an hdmi to analog converter for 50 euros. At least the audio is in sync with the video and the sound is fine. – Christopher Lowden Mar 4 at 20:31
