      Hi everyone,

      I'm having issues with my system, for some reason raspi-config can't detect any audio inputs despite being connected via HDMI.

      It won't detect any 3.5mm or USB inputs either. I'm using the HDMI port right next to the power unit.

      I'm also using a Pimoroni X-Hat (I tried connecting wires to the X-Hat's audio connector and it didn't detect anything, and I also tried removing the X-Hat and it still won't detect audio).

      Sometimes, when in Emulation Station in the sound settings, the volume will go to 100% (audio card) but as soon as I reboot it'll revert back to 0%. At that point I can't set the audio back to 100% - it'll reset back to 0%.

      I also don't have option to select Advanced Options - Audio so I can't force the audio through either the HDMI or the 3.5mm port.

      I had the audio work once, but I tried rebooting it after about 15 minutes and the audio now stops working.

      Here's my config file for reference, and any help would be amazing! Thank you!

        @chieferebus said in Retropie not detecting any audio inputs:

        It won't detect any 3.5mm or USB inputs either. I'm using the HDMI port right next to the power unit.

        I think you mean 'output' instead of 'input', the RPI has no built in audio inputs. Seeing that you commented out the audio=on dtparam in your config.txt, this may be expected.

        I also don't have option to select Advanced Options - Audio so I can't force the audio through either the HDMI or the 3.5mm port.

        Probably because you've disabled the onboard audio in the config.txt file. If you want audio via HDMI, revert your changes to the config.txt and make sure that

        dtparam=audio=on

        is not commented out. Reboot and then check again in the Audio menu the options available - choose HDMI / Headphones depending on what you want.
        In EmulationStation, choose default as Audio Card and the same value chosen in the previous configuration (Headphones/HDMI).

          @mitu Thank you! I don't think this forum would survive if you didn't lend a hand as much as you did. Resetting the config file to its default did the trick. For some reason, there was something in the file that wouldn't allow me to uncomment that "dtparam" line (it'd cause my screen to nearly fade to black completely, but clearly it crashed because I couldn't do anything except shutdown the Pi). For anyone with a Raspberry Pi 4 that wants the default config file this is what you need:

            For anyone with a Raspberry Pi 4 that wants the default config file this is what you need:
            ..

            This is not the default config.txt file, since the default doesn't have any picade overlay added or any rotate options (which is not supported on a Pi4 anyway). If you're looking for the default file, it can be extracted from the RetroPie image using 7Zip or by just mounting the .img file.
