      But ssh into the pi is giving me the same audio error as above

      What's the output of:

      aplay -l
      amixer
      

      I see in the config that the on-board audio is not disabled, but the audio is also configured over the GPIO pins with the pwm-2chan and pwm-audio-pi-zero overlays, which might not work 100% on the new model.

          I spent a good amount of time now on trying to figure out what is the problem. I don't think it's the overlays, since when you use a video splash screen, it gives out sound. It's probable that the splashscreen package uses pulseaudio while everything RetroArch related doesn't.

            No, it's not the splashscreen. The errors come from ES, which is not related to the splashscreen at all.

              Do you have an $HOME/.asoundrc or /etc/asound.confg file ?

                @philcomm okay that's interesting, I didn't notice that. I just tested a splashscreen with audio and it did play the sound for me too, no errors.

                I tested out the beta of the recalbox image they have and it played audio as well, so it does seem workable somehow, there config file is quite different though, I always thought the config.txt is universal to the raspberry pi itself, rather than the OS etc?

                    @retropieuser555 Is this before adding the RetroFlag's drivers/scripts or after ?
                    Normally, on a clean install, none of the files are present. Since aplay doesn't list any sound cards, the error you get in ES is normal, but I'm wondering if the GPIO connection on the RetroFlag case don't need additional configuration.

                    The splashscreen uses omxplayer to play sound, which bypasses any ALSA configuration, but EmulationStation (and most of the emulators) need a working ALSA config.

                    I always thought the config.txt is universal to the raspberry pi itself, rather than the OS etc?

                    No, it's specific to the RPI bootloader, but there are other boot methods (U-Boot perhaps) that don't use the file.

                      @mitu This is after adding the config.txt and overlays that the retroflag gpi. I can test it with the stock config.txt and original dpi24 overlay if that helps?

                        After further testing, I can't get either alsa nor pulse to work as sound drivers.
                        alsa doesn't find any sound card, thus is not able to play.
                        pulse can find the virtual sound card, but cannot output sound for some reason.

                        @mitu you are right, sound plays just fine with omxplayer.

                        I don't think it's the GPi cases' fault, but rather the drivers not able to play over GPIOs?

                          You can do that, but - at best - you'll get sound only on the HDMI port, which is not what you want. But this configuration should get rid of the ALSA error and you'd have at least one card listed by aplay.

                            @mitu you think it's worth a shot trying to manually create the asound.conf file?

                              Do you still have that image? My download is super slow, it takes another two hours to finish (around 60kb/s)

                                  @retropieuser555 I wonder if there is any difference in the /boot/config.txt file compared to RetroPie. Also, is the md5 hash of /boot/overlays/pwm-audio-pi-zero.dtbo the same?

                                    They don't seem to be using the pwm-audio-pi-zero.dtbo overlay in the config and it isn't in the overlay folders at all. Any ideas how they got this working? Guess can go onto their forum and ask them

                                      @retropieuser555 Does the /etc/asound.conf file exists? If yes, what's the content?

                                            Hi, I have been struggling with the same issue, and have managed to solve it.

                                            The issue is that by default the latest version of Raspbian disables the audio if nothing is connected to HDMI.

                                            Use this one line entry in config.txt to fix it:

                                            dtoverlay=audremap,pins_18_19,enable_jack=on
                                            

                                            You don't need the pwm-audio-pi-zero.dtbo file and you can remove all the custom audio entries from Retroflag's config.txt and use this one line instead. (leave all the entries for the LCD in obviously).

                                            The custom asound.conf file in recalbox is used to downmix stereo audio to mono, as the built in speaker on the GPi only outputs the right channel.
