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.
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:
Any ideas would be most grateful. Thank you
