      Oh, another thing I noticed: After rebooting with snd-bcm2835.enable_compat_alsa=1, even removing that line from cmdline.txt didn't made the problems reappear.

      I did a bit more testing with this, and for me, taking out snd-bcm2835.enable_compat_alsa=1 did break things again for me. Putting it back made things work.

      So it may be that removing this line by me didn't break sound again because I also did set Headphone in the Retropie settings and es_settings.cfg. I'll test that hypothesis when I have the time, which, alas, may be not before friday.

      Thanks for more pieces of this puzzle!

        @Clyde thanks for your suggestions. I'm also experiencing freezes when trying to navigate games. Not sure if the navigation sounds or the videos but you seemed to discard this last one. I have tried switching off the navigation sounds and various settings in this post and in the sticky one by mitu. Could you let me know , just to have them all in one place, all settings you have at the moment? I have followed mitu's advice so my settings in emulationstation.cfg are (using headphone out):

        Audio Card: Default
        Audio Device: Headphone
        OMX Audio Device: ALSA

        I also have the compatibility line in cmdline.txt: snd-bcm2835.enable_compat_alsa=1

        Thanks!

          @kikeminchas I wonder if something changed in a recent update as my arcade now freezes when I navigate the console menus and I reach Atari. The GUI freezes up and I am forced to reboot via SSH. The only changes I've made recently is to disable onboard audio in config.txt to fix an issue introduced by a recent update that caused the order of my audio cards to keep swapping (HDMI Audio, Headphone audio and usb card audio - latter two kept swapping places). I also overclocked the RPI4 to 1750. I am suspecting either the overclock or some update.

            Just FYI, my Pi 4 wasn't overclocked when it froze reproducibly with Navigation Sounds = on until I applied the workarounds.

              OK, I managed to stop the freezes. First of all, I did another update, kernel and several other packages were updated (including ES) so this is for sure the first thing to do. I started all over again with the config changes. The main difference compared to what I had previously it's that I disabled the compatibility line in cmdline.txt. I then selected headphone as output both in ES and Retropie Audio Tools, rebooted and finally audio working both in ES and games and no freezes.

                I can confirm similar findings. Today I burned a brand new RetroPie image (the Pi3 one), ran a full update, then loaded a handful of roms with video snaps.
                Once the screensaver and/or previews kicked in, I started receiving the "Failed to find mixer elements" error, and the game videos had no sound in ES.
                All I had to do was change the audio device to HDMI in ES, reboot, and then the sound was restored.
                Clearly something is wrong with the default audio settings (is it PCM?).

                    These steps worked for me. Pi 4.

                    • snd-bcm2835.enable_compat_alsa=1 in /boot/cmdline.txt
                    • ran emultionstation-setup script and selected Headphones
                    • in emulation station I set:
                      Audio Card : default
                      Audio Device : master
                      Omx Player: Local

                    No I get sound through my external speakers + I have the mixer working in emulationstation

                      For those having same with latest OS Dec updates and Pulse Audio:

                      go to ES Sound Settings and change from DEFAULT to SYSDEFAULT with PCM

                      Now sound will be ok and sound bar will work again

                      Your friend,
                      2Play!

                        I registered just to give a heads up to this solution.

                        I too was affected by the "failed to find mixer elements" nag error before running a rom.
                        There are a LOT of forum post about this issue, all with different solution with mixed results.

                        This solution worked for me too on my Pi 3B+
                        Installed RetroPie on top op Raspian
                        I want the audio from the headphone jack, not HDMI

                        • snd-bcm2835.enable_compat_alsa=1 in /boot/cmdline.txt
                        • selected Headphones in RetroPie Setup
                        • selected ALSA in Raspi-Config

                        in emulation station I set:

                        • Audio Card : default
                        • Audio Device : master
                        • Omx Player: ALSA

                          @colosso25 Did you encounter any random "stops" for 1-2 seconds of the system? Because that's what me and some others experienced using the headphone jack. The only solution that we found was to use HDMI sound.

                            @clyde This issue seems relevant - https://github.com/raspberrypi/linux/issues/4610. Try using audio_pwm_mode=1 in config.txt and see how it works.

                              No, not that I know of. I haven't been testing stuff out at that time. I was looking for a solution to this problem.
