I'm getting an audio error when previewing a shared link in a browser on iOS only.

What version on iOS are you using? 

Hi phonghjx, thanks for bringing this to our attention.

Which browser are you using on your mobile device?

Have you tried changing the dl=1 to raw=1 in order for files to preview directly?

This will help me to assist further!

Hi phonghjx,

I'm an engineer that works on Dropbox file previews. I think there might be a few issues here. First, I recommend using raw=1 instead of dl=1, as Jay said. Second, Safari on iOS ignores the `autoplay` attribute on audio files, so you will still have to manually start the video. Third, I recommend removing the `type` attribute. Dropbox will avoid re-encoding audio files when possible, so streams may sometimes be `audio/mpeg` and other times be `audio/mp4`, depending on the type of the original file. Removing the `type` attribute lets the browser infer the content type. Following these tips, I was was able to get this <audio> element working on an iOS device: 

<audio controls>

Your browser does not support the audio element.
</audio>

Thanks for posting in the forums!
