Audio 3.5mm Jack not working

[LMM]

It's odd:

Code:

# cat /proc/asound/cards

cat: can't open '/proc/asound/cards': No such file or directory

Code:

LibreELEC:~ # amixer -c 0 scontrols
LibreELEC:~ # amixer -c 1 scontrols
amixer: Mixer hw:1 load error: No such device or address
LibreELEC:~ #

May be a problem specific to LibeELEC kernel (sound card module not loaded ?
Some things to try to search the config :

Code:

aplay -l # list the cards
lsmod | grep snd # list the loadable module
alsamixer # for configuring the mixer F6 to change card

you will find many information in /proc/asound (kernel version, ...)

you could try to install a new version of libreElec (if it is not updated)

Sorry, I am don't know very well libreELEC, I rather use ubuntu or debian. 

I am curious to know where the pb comes from. Try the chat room, you may have quick answers.
