--- Comment #3 from Adrien Fernandes adrien_fernandes2@hotmail.com --- I tested a lot more games since I posted this issue.
So... I didn't try the entire games I have on Win7 setting but I can tell that not ALL games are having audio issues when set to Windows 7, it's pretty game-specific.
Actually, I do have that "Win7 audio issue fixed by setting to WinXP" but we can not just use that workaround in 2020 since Steam can not be started in WinXP.
Resident Evil: Revelations (Steam only), for example, is suffering of that "Win7 and higher audio issue" fixed by switching the prefix to WinXP. Back in the days when Steam were usable with Wine prefix set to Windows XP, I could use it as a workaround to play and finish it ! Now I can not anymore.
The Witcher 2's audio is working like a charm even when set to Win7.
Rogue Legacy & Necropolis are two games suffering of this issue too. Setting them to WinXP fix the audio. Since they are available through GOG, WinXP is still a possible workaround.
Assassin's Creed is bought on GOG so I can set it to WinXP. Yet, for THIS game (and possibly Far Cry 3 but not entirely sure), it won't fix the audio issue.
The audio behavior is exactly the same on Win7 and WinXP so I think that, even if Assassin's Creed's audio issue sounds a bit similar to the general "FreeBSD audio bug where games are stuttering and slowed down when set to Win7 and higher", MAYBE this is a separate issue and requires to be treated differently ?
I updated to Wine 5.0 and this is still an issue.
