Game audio gets weird if you are using virtual surround sound. I am using a pipewire 7.1 config, and hovering over buttons would make the sound go to the right ear for a short moment, and when in-game I could only hear voices from the left ear, etc. You can check this in pavucontrol: if you uncheck the lock, it will show more than two audio channels/sliders. The fix is to set the default audio as normal stereo (two channels, like regular headphones), then launch the game. After that, if you unlock it in pavucontrol again, it will only show two channels/tracks and the audio works like normal stereo. I haven't had this issue with other games, so I don't know what's going on here, virtual surround sound config makes something go wrong.
If you are not using any audio setup like mine, this won't be a problem, but I decided to write this in case anyone else faces this issue in the future.

OP/ED videos now work perfectly when using GE-Proton9-11 (GE proton version downloaded through ProtonUp-Qt, available on the deck Store)
It now DOES NOT NEED ANY FLAGS to run besides specifying GE Proton version under Properties (I only tested the latest GE proton 9-11 version listed above). First time opening might take a while as it generates the require files and cache; WAIT FOR IT TO FINISH. you may have to open it more than once if nothing opens after the first time.
The above guide may apply to other Yuzu games where WMP was needed.
Seamless afterward. And it was glorious.

桌面全屏模式下不能点击高级设置
在使用GE-Proton9-5并开启视频渲染自动模式下,使用游戏模式无法正常播放oped,在桌面模式下可以正常播放但有些音频播放不正常。
Using GE-Proton9-5 and auto video rendering, the OP/ED cannot play properly in game mode. However, they play correctly in desktop mode, though some audio issues are present.

In Steam Deck Desktop Mode with fullscreen, moving the mouse cursor to top menubar may cause the mouse click not working. Using Alt-Tab to switch to other windows and then switch back to the game can fix this problem.
GE-Proton9-5 has added fix for the game, OP and ED can play without install wmp9. However, it takes a while to launch for the first time.

PROTON_USE_WINED3D=1 %command%
使用的Proton版本为9.0 (Beta),游戏需要通过安装WMP9来解决视频播放问题(WMP11没有提供MFPLAT会导致游戏崩溃,我没有尝试过去补齐),同时需要在桌面模式下在游戏中更改高级设置,将视频渲染模式变更为自动(否则可能会出现视频不播放、视频模糊不清的问题),在Steam中设置启动选项PROTON_USE_WINED3D=1 %command%(使用DXVK的情况下播放视频时画面会闪烁)、设置游戏启动分辨率为1280x720,缩放模式设置为整数插值(不设置分辨率会导致视频播放时丢帧、失真、快进、闪退)

Not all movie playbacks could be played. But at least the game is playable from start to finish.
PROTON_USE_WINED3D=1 %command%
At the end of Koharu's route, the ED song could cause the game to hang (the ending song could still be heard in the background). So I was not able to get the achievement for completing her route. After some tinkering, I managed to resolve this issue by selecting the last option of "Movie Rendering Mode" in the 'Advanced Settings' (you need to press 'ALT' to bring up the menu and then select another option to display the hidden 'Advanced Settings'.) The movie still could not be played; however, at least I could get past it and get the achievement.

PROTON_USE_WINED3D=1 %command%
install wmp9
In Desktop Mode with fullscreen, moving the mouse cursor to top menubar may cause the mouse click not working. Using Alt-Tab to switch to other windows and then switch back to the game can fix this problem.
Install wmp9 to play OP

PROTON_USE_WINED3D=1 %command%
Install via protontricks:
- wmp9
Refresh Rate:
- 60 hz
Thermal Power (TDP) Limit:
- 4 Watts
Windowed mode may crash the game (when hovering the top menubar)

PROTON_USE_WINED3D=1 %command%
install wmp9
In Desktop Mode with fullscreen, when mouse pointer moves to top menubar, the game may freeze.
Install wmp9 to play OP
PROTON_USE_WINED3D=1 %command%
install wmp9
Install wmp9 to play OP.
PROTON_USE_WINED3D=1
Cannot detect keyboard input. In order to bypass the problem, for each time the game is launched you need the following steps. Go to "Settings" -> "Text" -> "Font" -> Press "Cancel" during font selection. The keybaord mapping should work as intened afterwards.
Proton GE recommended. Using the official version cannot render the videos and the game may freeze.
PROTON_USE_WINED3D=1
wmp11 required for video playback
Work like a charm using Proton 7.0-6 and the "PROTON_USE_WINED3D=1" command. Otherwise it will give a memory error and close. Installing WMP11 via protontricks is just optional so you can watch the Opening and Ending video.

I don't know about other versions, but GE Proton works nicely along with PROTON_USE_WINED3D=1 (wine d3d is a must use, idk about GE Proton)
The only proton version that worked for me was Proton 4.11 with protontricks 1144400 wmp11 and PROTON_USE_WINED3D=1 %command% launch option.
PROTON_USE_WINED3D=1 to fix black screen
protontricks 1144400 wmp11
启用 Wine D3D(PROTON_USE_WINED3D=1)以解决全屏时黑屏问题
需要安装 wmp11 才可以在游戏中播放视频(例如OP/ED)
即使玩家不使用特定版本的 Proton 且不安装 wmp11,受影响的内容只有视频相关,游戏的主要剧情内容是完全开箱即用的,不需要额外进行调整
Black screen if not enabled
PROTON_USE_WINED3D=1
with Proton 4.13 avoids this.
Use winetricks
or protontricks
to install Windows Media Player 11, or video playback will be broken.
Generally works out-of-the-box, but sometimes severe display problems occur...
After 12 hours of playing, the game window is refusing to refresh unless I send an windows resizing event to it. I didn't change my hardware configuration or system configuration prior to the time this problem happens.
PROTON_USE_WINED3D=1 %command%
launch option to not get black screen like the other Yuzusoft games
Tried protontricks 1144400 wmp9
at first and there seems to be some issues installing it, but then used protontricks 1144400 wmp11
and everything seems okay including movies.
Fullscreen not full, but only if you switched between fullscreen and windowed - if you start the game on fullscreen then there is no issue. No issue on windowed mode, click registering seems to be accurate too.
Sometimes during scene transitions, the game could crash due to (from the message) a memory handling issue, however it seems to be partly due to using Proton 4.11. Crashed twice during common route, but after that I experienced no other crashes, so just save often.
I tried Proton GE, but with Proton GE 6.12-GE-1 at least, even with protontricks wmp9/wmp11, the movies doesn't play, although unlike with normal proton 5.0 to 6.3 it does at least skipped through the movie segment without an error.

With latest Proton-GE. you don't need to seperately install wmp9 anymore for videos. PROTON_USE_WINED3D=1 is still needed, though.

The game with scene patch works flawlessly (including video playback after installing wmp9).
Installing wmp9 fixes video playback issues.
Installing wmp11 to the game prefix solve the issues of video playback
The launch option is not needed for the 4.11 branch.
Out of the box the in-game videos (opening, cut-scenes if any) will be skipped. To work around this modify a copy of winetricks and then use it either directly or via protontricks to install wmp9.

The launch option is not needed for the 4.11 branch.
The in-game videos (opening, cut-scenes if any) will not play, they'll be skipped instead.
