Im having the same problem when I preview on my iphone. Does anyone have any suggestions on how to fix this?
What is the bitrate of the MP3? Keep in mind mobile platforms have lower bitrate limits than PC's. I'd make sure they're not super high bitrate MP3s. Ideally really in the 72 range
Thanks for the quick reply. Turns out that it was working as expected. Like a dumbass I had my phone muted.
