FiiO has released firmware V2.40 for the SNOWSKY DISC portable music player. The update adds wireless control through FiiO Control, expands playlist and display functions, and addresses several practical faults involving Bluetooth-receiver output, unexpected restarts and music-library scanning.

## Update summary

- **Brand:** FiiO / SNOWSKY
- **Product:** DISC
- **Firmware:** V2.40
- **Release date:** August 24, 2026
- **Verification status:** Officially confirmed; independent post-update testing pending
- **App requirement:** FiiO Control 4.5.0 or later for wireless control
- **Update method:** Official manual firmware package is available; exact OTA availability by starting version and region is Pending verification

## What V2.40 adds

DISC can now be controlled wirelessly through the FiiO Control app. FiiO also adds support for custom lock-screen wallpapers, multiple custom playlists, M3U playlist import and export, and an optional CD-number display for album tracks.

Volume memory has been expanded so the player can retain a separate level for each working mode. This may reduce unwanted level changes when moving among local playback, USB audio, Bluetooth and other operating modes, although SoundPath Lab has not yet tested the transition behaviour.

## Faults FiiO says it fixed

FiiO lists three practical repair areas:

- no audio output on the first connection in Bluetooth receiving mode;
- unexpected restarts;
- song-scanning bugs.

The official note does not identify the exact conditions, frequency or hardware batches associated with the restart and scanning faults. V2.40 should therefore be treated as an official attempted fix, not proof that every historical restart, Bluetooth or library complaint has been eliminated.

## FiiO Control 4.5.0 is required

Wireless app control requires FiiO Control version 4.5.0 or later. The iOS 4.5.0 release also explicitly added DISC support. Users with an older app version should update the app before concluding that wireless control is missing from the player firmware.

Android version parity and regional App Store timing remain Pending verification.

## Update method and precautions

FiiO provides V2.40 through its official DISC firmware thread and download package. The cumulative instructions also discuss online updating, but FiiO does not clearly state whether every earlier DISC build in every region can obtain V2.40 by OTA.

Before updating:

1. Confirm that the product is SNOWSKY DISC and that the package is V2.40.
2. Note the installed firmware version and current playback, Bluetooth and library behaviour.
3. Keep the player adequately charged and do not interrupt power during installation.
4. After updating, confirm the firmware version before testing wireless control.
5. Use FiiO Control 4.5.0 or later.

FiiO does not publish a V2.40 rollback method. Users who depend on a particular Bluetooth, USB or library workflow should test that workflow before deleting an older local firmware package or changing their music-library structure.

## Does this resolve a SoundPath Lab Product Issues record?

No existing public SoundPath Lab Product Issues ID precisely matches these DISC faults, so no issue status has been changed.

The firmware note is strong evidence that FiiO recognized and addressed the listed behaviours. A future Product Issues record could move to **resolved-pending-verification** only if it is tied to a precise model and symptom; **resolved-verified** would additionally require reliable post-update confirmation.

## Verification note

Version, release date, app dependency, feature additions and listed fixes are taken from FiiO's official firmware record. SoundPath Lab has not independently tested update success, Bluetooth first-connection behaviour, restart frequency, song scanning, mode-specific volume memory or rollback.

## Revision log

- **August 27, 2026:** Initial verified draft based on FiiO's V2.40 firmware record and FiiO Control 4.5.0 App Store listing.
