Extract working link from m3u8-file

[loner]

Hi,

I'd like to save the audio file embedded in this site:

http://www.deutschlandradiokultur.de/aufstieg-eines-wanzenkillers-der-kammerjaeger.1034.de.html?dram:article_id=349833

I figured out a link to a playlist-file:

http://dradiohls-vh.akamaihd.net/i/2016/05/09/drk_20160509_2130_42f3eec4.mp4/master.m3u8

But the mp4 file in it doesn't exist. A few weeks ago it was possible to download the files in mp3-format from this site.

The links had the following structure:

http://ondemand-mp3.dradio.de/file/dradio/2016/05/09/drk_20160509_2130_42f3eec4.mp3

Any suggestions how I can download this funny radioplay by Bill Fitzhugh?
