S2member: how to play download protected mp3 files?

Dear people,

I’m trying to make mp3 files, which are protected from download, playable for members. I’m using the S2member plugin.

This is what i have attempted:

Shortcode audio player on Wordpress page:

[audio mp3=internetadresswebsite/?s2member_file_download=welkomstwoord.mp3&s2member_file_remote=yes"][/audio]

Download options (S2member) > Inline extensions: mp3 completed.

It seems to work for some mp3 files, but not for the most: it’s not clear for me why.
(It even does not work for example when i copy a working shortcode to another page: on that other page the mp3 is not found and not playable).
Is there something special i have to do, to make things work?

Thanks already for the answer,

Peter

You are missing an opening " but you are also over-complicating things. Try this:

[audio mp3="?s2member_file_download=welkomstwoord.mp3"]
