Hi, @LeHerosInconnu Are you using MIDI? I believe this issue is valid only for MIDI sound, while for external music I cannot reproduce this problem.

Hello @Branikolog,

Hi, @LeHerosInconnu Are you using MIDI? I believe this issue is valid only for MIDI sound, while for external music I cannot reproduce this problem.

Yes, MIDI is used when the problem is detected. I did a test with .ogg files in the MUSIC folder and "Music Type" set to "External" and the problem is no longer present. There must have been a change in MIDI management at some point.

There must have been a change in MIDI management at some point.

This was always the case. MIDI playback (more precisely, MIDI playback startup) is slow in SDL_mixer. Here is the video of fheroes2 1.0.0 released Dec 21 2022 (more than a year ago):

As you can see, there is the same pause that caused by delay of playing the WAV musical effect for this Shrine caused by MIDI soundtrack change due to the change of terrain. This is the same place, but using the Windows built-in MIDI (not FluidSynth MIDI) - i removed the soundfont file to force SDL_mixer to switch to the Windows MIDI:

The same delay (approximately +/-). We tried to mitigate this at the time by moving the background music playback to a separate thread, and it's just that when crossing the border of the terrain it's almost unnoticeable (except for some extra horse step sounds maybe), but in situations like this it will be noticeable with MIDI, because SDL_mixer cannot start MIDI music (which, again, is a rather slow operation) and play WAV file at the same time, because it's not thread-safe. There's not much we can do about it right now. Do not use MIDI :)

This delay is not observed with prehistoric 0.9.11, but the only reason is that in that version background music changes AFTER the object is visited, consider (turn the video sound on):

And the MIDI playback itself was problematic even then, it was just a bit disguised in this particular case. Regarding horse steps, in this video (also with prehistoric 0.9.11) you can hear how the horse steps sounds continue a little even after the hero stops on the new terrain, because their playback has been delayed a bit during the MIDI music change due to change of terrain:

And so far it can't be any other way.
