Unconfirmed（待确认）: the results include a short Huss Valley-labeled audio upload. This review did not listen to it or identify a whistle in a target clip. The metadata does not confirm the sound.
Basis: Two audio listings were captured as metadata only; the sound and its relationship to Huss Valley remain unknown.
The captured Audio.com page is titled Huss valley OG and displays a 16-second duration. A Voicemod sound page uses Huss Valley theme song in its title. Neither page was auditioned, so neither identifies a verified whistle sound.

Which whistle results were collected?
Audio.com lists Huss valley OG under the name DJ Fungus and shows a duration of 16 seconds. The visible page also includes the word whistling among its tags. Those are page fields, not a listening observation of the recording.
Voicemod Tuna has a separate page titled Huss Valley theme song and associates the result with a soundboard upload. The captured text includes other sound entries as well. The page was not played, so its title cannot verify a specific whistle or a source track.
Why the sound is still unconfirmed
The current materials do not contain a listening note that matches a whistle to a particular Huss Valley video. A tag such as whistling can describe how an uploader categorized a file, but it does not prove that the sound is audible in the recording. No official game audio source was found in the supplied materials.
A YouTube candidate in the whistle search had no available transcript, while a long-loop candidate has captions but was not auditioned. Caption status cannot identify a short instrumental sound by itself. These gaps leave the exact whistle, upload, and clip relationship unresolved.
Current answer
The collected pages provide leads for audio review, not a verified whistle identification. The Audio.com page is short and labeled Huss valley OG, while the Voicemod entry is a soundboard-style upload. The sources do not confirm that either is the sound heard in a Huss Valley meme.
A future check would compare a specified clip with a playable source and note the exact time of the sound. It would also preserve the uploader and title separately from a verified author or composer. Until that comparison is recorded, this page keeps the identification marked Unconfirmed（待确认）.
