      Description: On many sites you can find .mp4 videos in html5 players. These videos may contain several audio tracks. The problem is that Opera in such files plays the last soundtrack instead of the first one, as it should be.

      Steps to reproduce: I created such a file, there are 2 soundtracks in it. You can see it here: https://1drv.ms/v/s!AjFqXJlpTvaHrDuLtZR6nig20L18

      Actual result: When play in Opera, you will hear a sound: "Soundtrack number two".
      When play in Edge, Chrome, Firefox you will hear a sound: "Soundtrack number one".

      Expected result: Must hear the sound: "Soundtrack number one".

      OS: Windows 10
      Version of Opera: Opera 45.0

      P.S.: Recently, my partners sent me a video https://1drv.ms/v/s!AjFqXJlpTvaHpDkb9RaWuJJSnRcv I have an error and I can not see it in Opera. But in Edge, Chrome, Firefox it plays correctly.

        And it has nothing to do with this topic so please open a new one for that issue.

          Do you have some other examples?

            Pulled a direct link from animaunt.ru , russian site with cartoons http://online.animaunt.ru/Anime Online/Spring Ongoing 2017/[AniMaunt.Ru] Natsume_Yuujinchou_Roku/Natsume_Yuujinchou_Roku_[06]_[AniMaunt.Ru].mp4
            1 track in Russian, 2 in Japanese. Opera plays 2 track.

                I see Vivaldi plays the wrong track too.

                  Another example: http://hdd.anipower.ru/Fullmetal_Alchemist/2/2.mp4
                  1 soundtrack - Russian.
                  2 soundtrack - Japan.
                  Edge, Chrome, Firefox plays this video with Russian language.
                  Opera plays this video with Japan language.
                  The video should play Russian.
