Marvel Rivals Sound Effect and Music Mods Not Working? How to Fix Them
Sound-effect, emote, MVP and music mods for Marvel Rivals stopped playing for most players after a September 2026 update, the same update that broke voice mods. RIVALSFPS.GG 5.3.0 fixed voice mods. 5.4.0 extends the same Fix to the rest: it converts each mod so its sounds play again and backs up the original.
Why they stopped playing
Since the September 2026 update, Marvel Rivals closes, or unmounts, mods
packaged as plain .pak files shortly after it starts. Most
of the game's sounds load later than that: a hero's ability sounds when
the hero is picked, an emote when it plays, the music when a menu or the
lobby opens. By then the mod is closed, and the game plays its own
sounds as if the mod were not there.
Fix gets around it by moving the sounds a mod changed into sound files the game loads at startup and never closes. Only the sounds the mod's author replaced are carried over, so a mod made before a game patch does not undo what the patch changed.
Fix a sound mod in RIVALSFPS.GG
- Update RIVALSFPS.GG to 5.4.0 or later and close Marvel Rivals.
- Open the Mod Manager. Your sound mods are in their own Sound Mods section.
- Click Fix on any mod marked Outdated, or use Tools > Update my mods to update every outdated mod at once.
- Start the game with Launch and listen for the sound in the practice range, or on the menu for a music mod.
When a run skips some mods, the result lists them grouped by reason. Mods that 5.3.0 marked Can't update with "Fix can only update voice lines for now" are checked again after you update.
What Fix converts
| Kind of mod | What happens |
|---|---|
| Voice and ult lines | Converted since 5.3.0 |
| Sound effects | Converted. A mod for one hero's abilities changes only that hero; the others keep their own sounds. |
| Emote and MVP sounds | Converted |
| Music | Converted, such as the menu and lobby tracks |
| Loose audio files | Converted when they sit in the game's audio folders. Each file replaces every sound that plays it. |
Converting sound effects and music is still experimental. If a converted mod sounds wrong, put the original back with Restore original and make a ticket in our Discord with the mod's name and where you got it.
Undo it: Restore Original Sound Mods
Every converted mod's row has a Restore original link that puts back the file it was converted from, exactly as it was. To undo all of them, open Tools in the Mod Manager and pick Restore Original Sound Mods. It lists the mods first and asks before it changes anything, and each mod keeps its on or off switch. A mod that can't go back, for example because its backup is missing, is listed with the reason and keeps playing as converted. You can run Fix again later to convert them all back.
Several sound mods at once
Each sound mod has its own switch, and every one that is on plays. The app combines them into one file the game loads and rebuilds it when you switch a mod on or off. When two mods change the same sound, the one listed first plays and the other gets a red Conflict badge naming it. Switch the winner off to hear the other.
A converted sound mod someone shares with you, a .rfsound
file, imports like any other mod since 5.5.0: press
Import in the Mod Manager or drop it on the window.
What Fix still can't convert
A mod Fix can't convert is marked Can't update. Hover the badge for the reason. The common ones:
- Loose audio files outside the game's audio folders, where nothing says which sound they were meant to replace.
- Mods that change sounds the game no longer has.
- Mods that only change volume or pitch, with no audio of their own to carry over.
- Mods whose audio is incomplete, or in a format Fix can't read.
- Mods that would come to more than 512 MB of audio.
For these, look for an updated version of the mod made after the September update.
Common questions
Why did my Marvel Rivals sound-effect and music mods stop working?
Since a September 2026 update, the game closes mods packaged as plain .pak files shortly after it starts. Most sounds load later, when a hero, a match or a menu needs them, so by then the mod is closed and the game plays its own sounds.
How do I fix a sound-effect, emote or music mod?
Update RIVALSFPS.GG to 5.4.0 or later, close the game, open the Mod Manager and click Fix on the mod marked Outdated, or run Tools, then Update my mods, for every mod at once. The original is backed up first.
How do I undo it?
Click Restore original on the converted mod's row, or pick Tools, then Restore Original Sound Mods, to put back every sound mod Fix converted at once. Each mod keeps its on or off switch.
My converted mod sounds wrong. What do I do?
Converting sound effects and music is still experimental. Restore the original from its row, then make a ticket in the RIVALSFPS.GG Discord with the mod's name and where you got it.
Do I need the Unmount Blocker for sound mods?
No, and players running it have reported warnings and bans. Fix converts sound mods so they play without it.
