I fixed the missing cutscene audio issue following this user's guide and script to fix a different game: https://www.protondb.com/app/658260#wLSKQR4IhP
The solution is to change the audio codec to PCM audio (with for example ffmpeg).
Open up the install directory for AYESHA (in Steam, right-click on the game -> Manage -> Browse local files), go inside the directories Res/x64/movie/
Create an empty file in there named "fix_videos.sh" (without the quotes), open it, and copy and paste the following into the file:
#!/usr/bin/env bash
for wmv_file in *.wmv
do
new_filename="$wmv_file".ORIGINAL
echo "Renaming $wmv_file to $new_filename"
mv "$wmv_file" "$new_filename"
ffmpeg -i "$new_filename" -acodec pcm_s16le -vcodec copy "$wmv_file"
done
Open up a terminal in the /movie directory and run the following:
chmod +x fix_videos.sh
./fix_video
The script will backup the original files.
Laucher requires mouse input via trackpad or touchscreen
Audio missing from cutscenes when using Custom Proton: GE
All credit belongs to the user linked above. I tried all different suggestions to get the cutscene audio working and this is the only fix that worked for me. You must run the game using a proton-GE custom compatibilty tool (I used GE-Proton9-11) for this fix to work.
Fix will need to repeated and applied to all files containing wmv video files. For example, these are the other directories I applied the fix to
- Res/x64 /movie_EN
- Res/x64 /movie_EN/Jpn
- Res/x64 /movie_EN/Eng
After the fix, the game appears to run perfectly

Played the game in Japanese. No issues whatsoever with the default settings. Videos played with audio.
In short, works perfectly.

Disable proton media conversion or videos will have no sound
Fullscreen grsphical glitches
Finally figured it out and got cutceenes working, use GE and disable proton media conversion via launch command. Play in windowed mode.

During loading, after that, Alt-Tab functions normally
Sometimes keyboard input are not registered
Fixed with Atelier Sync Fix
If you use Proton-GE or Wine-GE and experience any problem, such as crashing on main menu, switch to vanilla.
Fullscreen causes graphical issues (see my previous report). Disabling fullscreen works best for this game, unlike the conventional wisdom on the Deck.
Don't enable fullscreen and things work well - see last post for the video caveats.
Touchscreen or mouse emulation required to get past the launcher.
Audio is missing from videos when using GE.
After around 20-30 minutes of playing, some graphics (effects, some text) suffer from mild corruption that is only fixable when relaunching the game.
I've tried standard Proton, Experimental, and multiple versions of GE - they all have issues to various degrees. GE is the only one with fully working video, though at the expense of the audio for said video. I had persistent graphical issues no matter which version of Proton I was using - I haven't played on Windows so I don't know if they happen there as well. The game is definitely playable but it should probably be downgraded to Gold as there's still flaws to be fixed.
On proton experimental opening movie and some random town intro movies work. Other movies show "broken video" screen. Ending crashes the game. With each experimental update I experienced when playing the game the list of working videos changed, so maybe it's being worked upon right now.
I suggest using GE7-49 currently. All movies work under it with no sound. Except for opening and ending credits all movies are VERY short and consist mostly of subtitles on the black background. At least they don't crash. All videos are available from the in-game gallery once you saw them, so if you have access to Windows you can watch them later with sound.
All in all the game works pretty much perfect. I completed most of it on SD. It's good to set the rendering to 1080p even when playing portable, as the game looks much better in that res (going higher doesn't work, as then the game renders in native 720p anyway). There's slight stutter each time a text window is shown, but it's like this on Windows as well, and it's known bug of all Dusk series games.
Most videos work fine, but introduction for the main city didn't play - I instead saw tv error-like screen.
As everyone mentions you have to use touchscreen or trackpad to interact with the launcher, but the buttons are huge. It uses very little power, I run it at 1080p (so it downscales to 720p) and with no tinkering it gets 4+ hours. I'm not sure if that was the only video that glitches or if there will be more later on, but most of the game is on in-game engine.

Have tried using Proton GE as well. But revert back to the recommended default
Without Proton GE the opening won't play. With it, it plays but there is no audio coming out.
Since the opening and probably other anime cutscenes did not have their audio playing, it won't matter much whether it plays or not, personally of course.
Laucher windows - Can be used well with touch input
Without extra tinkering or changing anything, you have to use touch screen for the starting window. Afterwards, the game works great, but it automatically skips the intro video.

Runs at 1280x720, fullscreen off. Launcher window requires interaction with touchscreen. Otherwise no issues. Solid 60fps, ~8-9W power usage.
Game runs fine like windows under proton 5.0.1.
a small freeze in the menu, for like 10 seconds
If running under any other proton version including GE, the game crashs on launch. I tried to apply the "atelier stutter fix" and the game didnt load the fonts. D3D or D3D11 crashes the game, even under 5.0.1. DXVK is the only way to go. Videos also do not load and jump straight to menu.
I had to switch to Proton 5.0-10 to get it to work.
Works great out of the box
Ran fine out of the box, no tweaks needed. Performance seems good.
Every time a dialog appears the game loads it in that exact moment, wich cause a really little freeze, on battles is a little bit worse, but it can be played without any tinkering.
To get the game to work past the white screen glitch the same fixes need to be applied as to other Gust ports
launch the game with PROTON_USE_D9VK=1 and put a dxvk.conf file in the game directory with the content: d3d9.deferSurfaceCreation = True
