This can only be observed on specific devices. I reliably reproduced it on a OnePlus AC2003 with Android 11 but customers of us reported it also on Samsung S10 with Android 11.

Please find the adb bugreport attached.

Steps to reproduce:

In the demo app define one DRM protected source and one clear source in a play list, e.g. as follows:

 List<MediaItem> mediaItems = new ArrayList<>();
      MediaItem.Builder builderProtectedItem =
              new MediaItem.Builder()
                      .setUri("https://storage.googleapis.com/wvmedia/cenc/h264/tears/tears.mpd")
                      .setMimeType(MimeTypes.APPLICATION_MPD)
                      .setMediaMetadata(new MediaMetadata.Builder().setTitle("DRM protected").build())
              .setDrmUuid(C.WIDEVINE_UUID)
              .setDrmLicenseUri("https://proxy.uat.widevine.com/proxy?provider=widevine_test");

      mediaItems.add(builderProtectedItem.build());

      MediaItem.Builder builderClearItem =
              new MediaItem.Builder()
                      .setUri("https://storage.googleapis.com/wvmedia/clear/h264/tears/tears.mpd")
                      .setMimeType(MimeTypes.APPLICATION_MPD)
                      .setMediaMetadata(new MediaMetadata.Builder().setTitle("Clear Sample").build());

      mediaItems.add(builderClearItem.build());

After starting playback of the first source, transitioning to the next source causes the described issue.

Edit: It does work when I configure both sources as DRM protected. Maybe that was the missing piece.

Ah yeah, that’s also a slightly sharp edge of the API: https://github.com/google/ExoPlayer/issues/8957

I did see that release note but I don’t think this helps here as the MediaItem is clear and there is no reason to actually use a DrmSessionManager at all. 🤔 But maybe I am missing something. (It did not work when quickly testing it in release-v2)
