        Hi, I have the same issue.

        Post the settings for audio that you have in EmulationStation (Card and Device). What version of DietPi ? Are you using PulseAudio/PipeWire for audio ? Is the audio working when you start a game/emulator ?

        Please run the following commands and post the output:

        amixer
aplay -l
aplay -L

          @mitu Hi Mitu, thank you for the response!

          I am running Dietpi OS v9.8.0 Armv8 Debian GNU/Linux 12 Bookworm
          Device model : Orange Pi Zero 2W (aarch64)

          Pulseaudio is installed, I've read elsewhere that it should connect to Alsa.?

          I do have sound through HDMI output, no matter what settings in ES.
          ES, Retroarch and Mupen64plus are fully functional, apart from the error.

          Extra info, proper hardware/software setup for the sound on Orange Pi Zero 2w might be incomplete. If so, and this is an OS issue, i'll move back to the Dietpi forum :)

          Hope this will already help identifying the issue:

            I was trying every setting yesterday and gave up. I gave up when it was set to: Default/Master

            I logged in to double check and... No more error.

              ...

              Since the default Mixer control for the default audio card is named Master , this is what you should set as Audio Device. As it turns out, you already found this is the working option.

                @mitu thank you for clarifying. If needed on a different device, I now know how to check it and replicate.

                    @hughp for me it was finding the correct setting. Default/Master
                    Try to replicate what @mitu said above. I was lucky to reboot with the correct setting by accident.

                    I believe a reboot will be necessary ater each time you check it, but not sure.

                    Again, I was lucky and Mitu was right the day after.

                      No, a reboot is not necessary.

                              @hughp No idea then. If the audio works in games, then the default device is set to headphone/analog on the system.

                              Please run the following commands and post the output:

                              amixer

                                I have the same issue.
                                Here is a short video showing it happening.

                                I have a fresh install as per instructions on https://github.com/danielfreer/raspberrypi5-retropie-setup?tab=readme-ov-file

                                Pi 5 connected via hdmi for audio.

                                I've tried the fixes that worked for some above, but nothing changes.
                                as per @mitu request I have run the amixer/aplay commands

                                pi@retropie:~ $ amixer
                                pi@retropie:~ $ aplay -1
