Raspberry Pi 4, LibreELEC 10.0.1, HifiBerry / PCM5122

    I have a I2S sound card HifiBerry type based on PCM5122, it's the only device connected to my raspi, and after update I cannot see it anymore.

    In my config.txt file I have added the line:

    Code
    dtoverlay=hifiberry-dacplus

    The troubleshooting guide (https://www.hifiberry.com/docs/software/no-sound-checklist/) from their website starts with "aplay -l" command, which for me shows:

    Code
    LibreELEC:~ # aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: vc4hdmi0 [vc4-hdmi-0], device 0: MAI PCM i2s-hifi-0 [MAI PCM i2s-hifi-0]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: vc4hdmi1 [vc4-hdmi-1], device 0: MAI PCM i2s-hifi-0 [MAI PCM i2s-hifi-0]
Subdevices: 1/1
Subdevice #0: subdevice #0

    This list should show "hifiberry-dacplus" but it does not.


    Further, there is a guide here: https://www.hifiberry.com/docs/software/…g-linux-3-18-x/

    For Linux 5.4 they suggest to disable the onboard EEPROM by adding:

    Code
    force_eeprom_read=0

    I am not sure which linux kernel is LibreELEC 10.0.1 using but adding this does not fix anything.

    Output from "sudo vcdbg log msg'

    Any suggestions please?

    Thanks. Do you use HiFiBerry DAC+ in standard edition (RCA version), or something else?

    PS: Try dtoverlay=hifiberry-dac (without the "plus", reboot necessary).

    I am using a generic breakout board for the PCM5122

    So, trying with dtoverlay=hifiberry-dac now shoes hifiberry-dac in the list of audio outputs, but hifiberry-dac is based on PCM5102 not on PCM5122 which I need so I get no sound.

    It is strange that one of them shows up and the other does not.

    I really doubt this to be the answer, as the PCM5122 is used in a lot of boards. IQaudIO also makes similar boards.

    After checking my hardware one more time it seemed that the connections made with wires were unreliable, so I just soldered short shielded wires and it solved my issue.
