Audio 3.5mm Jack not working - clement - 05-05-2020

Hello,

I installed LibreElec on my new ROCKPRO64. I have a hi-fi stereo which I want to plug on the audio jack 3.5mm. It doesn't work, meaning I don't have any sound. I don't know from were the problem comes from and I don't know how to investigate.

I post in general forum because I don't know if it's an hardware or Linux issue.

Thanks in advance for your help Smile

Hi,
I am not using LibreElec but Debian. But in order to enable the jack plug, I have first to enable the headphone mixer :

Code:
amixer set 'Right Headphone Mixer Right DAC' on
amixer set 'Left Headphone Mixer Left DAC' on

best regards.

Hi,

Sorry for the late answer, I didn't get notification by email.

Code:
# amixer set 'Right Headphone Mixer Right DAC' on
amixer: Unable to find simple control 'Right Headphone Mixer Right DAC',0

I have no idea how to adjust parameters.

If I understood properly, I can use

Code:
# amixer scontrols
# amixer scontents

to list the devices, but it doesn't return anything.

Code:
# amixer info
Card default 'HDMI'/'HDMI'
  Mixer name : ''
  Components : ''
  Controls      : 3
  Simple ctrls  : 0

for me, amixer returns :

Card default 'rockchiprk3399'/'rockchip,rk3399'
  Mixer name : ''

  Controls      : 35
  Simple ctrls  : 35

It seems that you are using hdmi output, therefore you have to switch the card.
You can probably use alsamixer command or

Code:
amixer -c 0 set Headphone playback 100% unmute

0 should be rockship sound card

Unfortunately,

Code:
# amixer -c 0 set Headphone playback 100% unmute
amixer: Unable to find simple control 'Headphone',0

what do you have with:

Code:
cat /proc/asound/cards

and

amixer -c 1 scontrols

RE: Audio 3.5mm Jack not working - clement - 05-24-2020

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

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.

RE: Audio 3.5mm Jack not working - clement - 05-24-2020

I have the last version of LibreElec. There is no update since I installed it. I also rather Ubuntu, however, video performance were terrible and each attempt to fix it lead to a broken system, and Kodi does pretty much everything I want.

The audio controller seems to be seen by the OS

Code:
# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: HDMI [HDMI], device 0: ff8a0000.i2s-i2s-hifi i2s-hifi-0 []
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: ES8316 [ES8316], device 0: ff890000.i2s-ES8316 HiFi ES8316 HiFi-0 []
  Subdevices: 1/1
  Subdevice #0: subdevice #0

No sound module loaded, but I don't know how the kernel is build, maybe the driver was not compiled as module

Code:
LibreELEC:~ # lsmod | grep snd

LibreELEC:~ #

alsamixer was not installed. I installed it and tried to change sound card but alsamixer crashed

Code:
# alsamixer
cannot load mixer controls: No such device or address

RE: Audio 3.5mm Jack not working - clement - 05-24-2020

I tried to rebuild LibreElec to check driver support on Linux kernel.

Code:
$ grep ES8316 LibreELEC.tv/build.LibreELEC-RK3399.arm-9.2-devel/linux-aa8bacf821e5c8ae6dd8cae8d64011c741659945/.config
CONFIG_SND_SOC_ES8316=y

So it is no surprise that

Code:
lsmod | grep snd

didn't return anything.
