No sound at all in The Elder Scrolls Arena (GOG) when launched through Heroic

[4Vertikal4]

Describe the bug

When running The Elder Scrolls Arena (GOG version) through Heroic Games Launcher, the game launches and runs correctly, but there is absolutely no sound - no music, no sound effects, nothing. The game is completely silent. Additionally I also tried the set up even though FluidSynth/QSynth, but it didn't work either.

Steps to reproduce

1. Install The Elder Scrolls Arena (GOG version) using Heroic Games Launcher
2. Launch The Elder Scrolls Arena from Heroic
3. Game starts and runs, but has no audio output whatsoever

Expected behavior

The game should have complete audio functionality, including music and sound effects, as it does when played natively on Windows or when configured properly through standalone DOSBox.

Heroic Version

Latest Stable

System Information

OS: Fedora 41 Workstation
CPU: 12th Gen Intel i5-12400F
GPU: NVIDIA RTX 3060 Ti
RAM: 16GB
Heroic installation method: Flatpak (system-wide)
Wine version: Wine-GE-Proton8-26

Additional information

I've tried extensive troubleshooting:

I FluidSynth/QSynth setup attempts:

1. Installed QSynth/FluidSynth: sudo dnf install qsynth fluidsynth
2. Downloaded soundfonts: FluidR3Mono_GM.sf3 to ~/.local/share/soundfonts/
3. Tried launching QSynth with various parameters: qsynth -a alsa -m alsa_seq
4. Verified FluidSynth was running using: aconnect -o | grep qsynth

II DOSBox configuration:

1. Located DOSBox config files: find ~/Games/Heroic/Arena -name "dosbox*.conf"
2. Found and reviewed /home/vertikal/Games/Heroic/Arena/dosbox_arena.conf and dosbox_arena_single.conf
3. Attempted to modify audio settings in these configuration files
4. Integration script attempts:
5. Created custom launch script at ~/.local/bin/play-arena.sh
6. Made it executable: chmod +x ~/.local/bin/play-arena.sh
7. Script launched QSynth before starting the game through Heroic

III Flatpak permissions:

1. Added device access: flatpak override --user com.heroicgameslauncher.hgl --device=all
2. Attempted to access Wine configuration: WINEPREFIX="/home/vertikal/Games/Heroic/Prefixes/default/The Elder Scrolls Arena" flatpak run com.heroicgameslauncher.hgl winecfg

IV Other attempts:

1. Checked system audio with other applications - works fine
2. Verified Wine prefix location and structure
3. Explored DOSBox MIDI and sound settings

Despite all these efforts, the game remains completely silent. I suspect there might be issues with how Heroic's Flatpak implementation handles DOSBox audio passthrough or Wine audio configuration for DOS games specifically.

I did additional troubleshooting:

Reproduction Steps:

1. Configured dosbox_arena.conf with [sblaster] sbtype=none and [midi] midiconnect="FLUID port".
2. Attempted starting FluidSynth with:

fluidsynth -s -a alsa -m alsa_seq "$HOME/.local/share/soundfonts/FluidR3Mono_GM.sf3" &

Result: Process is immediately paused/terminated (message "Zatrzymano"/Stopped).

3. Tried connecting MIDI ports:
   aconnect failed (Operation not permitted) due to permissions/Flatpak isolation.

Current Symptoms:

1. FluidSynth fails to run persistently (stops after starting).
2. MIDI connection command errors due to permission restrictions (even with sudo).
