Status: UNCONFIRMED

Steps to reproduce:

Open a page in Wayback Machine containing WAV audio (https://asciiexpress.net/gameserver/bc's_quest_for_tires.html)


Actual results:

Audio controls showed a long duration time. When the sound is played to the end or seeked past the real sound duration, the seek bar snaps to the end


Expected results:

The audio control bar should display the real duration

Attached is a simpler example. Left is from the original source, and right is from Wayback Machine, which does not include a content length header

Why is this not considered to be a bug in the Wayback Machine?

I cobbled together a local server in NodeJS, and explicitly set it to not serve a content length, and the issue (sometimes) manifests there too

[doomtay]

With a cache buster and no content length header, the issue always manifests

This also happens with wav files encoded as data urls
