      @Duveldg I see it after I select a game in EmulationStation (the screen goes black, it's not actually in EmulationStation) but before the runcommand prompt appears

        Ok that I don't see anymore. I have changed the audio driver for alsathread to sdl2 in all emulators because I did not have sound. Before that I saw the error I think.

          I started getting the same errors immediately after installing Kodi 17, if I remove it they go away. I do get semi frequent sound issues now when gaming but just learned to deal with it

            @gopherguts420 Does it appear only when launching Kodi first, or also if use any emulator withouto using Kodi ? Do you notice any sound issue when you see it ?

              Did you ever get this resolved? I'm having this problem now too. Granted, this topic is 3 months old, and it might have been fixed in a new version of something. I haven't updated any of my stuff in that long a time. Just curious.

                  Hmm.. reading about it says it has to do with the driver not getting samples fast enough to play back. I just started scraping a bunch of video snaps for my system and notice the stack of errors when a game launches after I've spent awhile looking at videos. Might be the videos causing the problem..

                    @hansolo77 I've never had video previews on any of my systems. I do try to keep them up to date with the latest RetroPie build. I check every few weeks or so.

                      Yeah I'll try updating and see if it goes away.

                        I'm also getting this, with a fresh install of 4.2 on top of Ubuntu 16.04.3 (for the Odroid XU4).

                          @raelik I just bought an Odroid UX4 and installed Retropie. As soon as Emulation station loads I can see the same ALSA lib underrun error. Any clues about what could be causing this?
