Output of Wine 4.21 running Assassin's Creed

So here it is, it might be a bit long and I'll try to be as precise as I can to
explain the problem.

First, list of tested games :

Far Cry 2 : No audio problem ✔
Crysis : No audio problem ✔
XIII : No audio problem ✔
Far Cry 3 : Crackling audio ✖
Assassin's Creed : Crackling audio ✖

I ran all the games set on DirectX 9 and I built Wine to use Open Sound System
for audio (if this is important). Assassin's Creed 1's prefix is set to WinXP
and Far Cry 3's one is set to Win7 (because of Uplay).

The problem is that the audio on Far Cry 3 and Assassin's Creed is weirdly
crackling and slower than it should be but, not EVERY sounds in the game are
making the audio crackles. On Assassin's Creed, it's when a lot of people are
around me and everytime I use the eagle vision. In the menu or when outside the
Animus (in the present time of the game where there are only three people and a
tiny room), the audio works well. Also, an important point is that neither
Assassin's Creed nor Far Cry 3 are slowed down to fit the slowed down audio
issue. They both work very well when it happens which is causing a strange
issue I'll describe AND SHOW below.

I'm using a GTX 765m to play which is not bad for old games like these.

"Your computer certainly isn't powerful enough to run the game !" you say...
Well, you are not totally wrong, I could have better hardware but, in the past,
when I was playing these games on Windows then, later, on GNU/Linux, I never
met this problem. The two differences are that I'm playing, for the first time,
Assassin's Creed _ON_FREEBSD_ and we are now almost in 2020. My last Assassin's
Creed session was on GNU/Linux in 2016. Wine changed so much in almost 4 years
!

But let me remind you that only two of the five games mentioned above are
having issue. all my native FreeBSD games (OpenMorrowind, Xonotic, Minetest,
Tales of Maj'Eyal, Quake II from Yamagi's source code etc...), videos read with
mpv, music listened with moc and even Firefox are all working well without
crackling or slowed down audio. And three tested games on Wine with OSS are
working perfecly. I could have tested more games but I think three is good
enough.

So here is the "show" I mentioned in the beginning. I took a video of
Assassin's Creed's problem. I recorded it with my phone so... sorry for the
poor quality but you can see the problem :

In this video, you can see two people speaking together. In the normal game,
one speak and, when finished, the other answer. They _NEVER_ speak above the
other. In my Assassin's Creed, the game is running well but the audio is slowed
down which creates a desyncing between the slowed down voice played and the
mouth of the character. And, because the game is running well beside this
issue, one didn't finish his sentence and the other will start his speech over
the first one (it shouldn't happen).

I found a longplay video of the game which is certainly played on Windows. I
copied the video link to start at the exact same moment as the one I recorded
from my computer and you can see how the game should normally behave :

About the crackling audio issue, it can be heard by the end of my video when I
use the eagle vision.

For Far Cry 3, don't even need to run the game to hear crackling and slowed
down audio. I also took a video of the problem, it speaks for itself :

The original theme can be listened here : https://youtu.be/rfAeL4JfHj8?t=10
I copied the video to start at the same time of my video of Far Cry 3, in the
menu. What you can notice is that the normal music is faster than in my video,
it's the same problem than with Assassin's Creed 1.

I fetched the output of Wine when running Assassin's Creed 1. It repeatedly
says two things so I cut it into "head -n 50" and "tail -n 50". I watched the
long output and nothing is different between the first 50 and last 50 lines.

I hope I was clear enough, English isn't my native language so I apologize if I
didn't use it correctly.
