Sorry this is rather late… if you’re still having problems, could you provide a link to your website so I can see?
Thanks for your reply. I’m still having problems. It’s not possible to play audio on mobile devices (Android an iOS) with PlayPress.
This is the link to my website: http://www.nem-q.com/discography/
You’ve provided a comma-separated list of multiple files, which apparently allows the Flash player to play several tracks in succession — I didn’t even know this was possible (!). It doesn’t work with the HTML5 player used on Android and iOS.
As it’s not an advertised feature of PlayPress, if you don’t want to have a separate player for each track, I’d suggest using a different plugin. In fact, WordPress has a great built-in audio playlist feature now (on the post/page editing screen, choose Add Media > Create Audio Playlist) which is good and can work on mobile devices. The end result looks a bit like this: http://make.wordpress.org/core/files/2014/01/Screen-Shot-2014-01-29-at-3.06.07-PM.png
Thanks for the feedback! I’m going to try the WordPress built-in audio playlist feature then.
