Hi! Can you reproduce your problem with an example, maybe with codesandbox?

[taskaijo]

if the backend parameter not 'WebAudio' it does not work

[entonbiba]

@zhangzygit can you provide a link to the audio file in question for testing?

[HYiteam]

backend: 'WebAudio'

@thijstriemstra , have you eventually solved the issue? what the cause was?

I believe the problem is how HTMLMediaElement behaves while setting its internal currentTime when the server serving audio files is not configured properly. Changing currentTime creates a byte range request for the server asking for a part of the audio file - and if this fails, the player sets currentTime to 0 by default.

I struggled for a while with this in one project since I had to serve the files with my own implementation. IIRC when I correctly handled the byte range requests Wavesurfer also began to work.

See this StackOverflow answer for reference.

Edit: Just noticed that it was katspaugh themselves that wrote the original stack overflow answer. 😄

@samuliedvin , thanks for advice. solved that by applying Accept-Ranges header.
