LibreElec/Pi Zero /DAC+ Zero/IR Remote Problem

    Hello,

    I have the following problem with a LibreElec 9.2.3 installation with a Raspberry Pi ZERO WH plus HifiBerry DAC + Zero card:

    I have entered the entry for activating the IR diode in the config.txt file, I can no longer get the DAC in the System / Audio menu.

    Only the standard output measures are available.

    Without the content << dtoverlay = gpio-ir, gpio_in_pin = 17 >> the DAC works perfectly

    Changing the pin number does not change anything

    Is there a solution to my problem?

    Thanks and regards Jonas

    Extract from the file config.txt:

    ################################################################################

    # End of default configuration

    ################################################################################

    # HifiBerry DAC

    dtoverlay=hifiberry-dac

    # Lirc

    dtoverlay=gpio-ir,gpio_in_pin=17

    ################################################################################

    Attached two log files:

    odi.old.log.txt = DAC works

    kodi.log.txt = DAC not availablekodi.log.txtkodi.old.log.txt

    There are 2 issues with your config.txt:

    Code
    dtoverlay=gpio-ir,gpio_in_pin=18

    you are still using "gpio_in_pin" instead of "gpio_pin" and also you can't use GPIO 18 - this is required by the I2S interface - dmesg/journal therefore prints this:

    Code
    Apr 11 18:28:51 LE923zero kernel: pinctrl-bcm2835 20200000.gpio: pin gpio18 already requested by ir-receiver@12; cannot claim for 20203000.i2s

    You have to connect the IR receiver to a GPIO that's not used by the DAC card, GPIO 17 should be fine, and then properly specify that in the dtoverlay line - eg gpio_pin=17

    so long,

    Hias
