I created two test posts, each with a separate mp3 file which is stored on mediamax.com (streaming is allowed).
Test Post 1. mp3 file of 12mb. On starting, it just says buffering and does not play at all.
Test Post 2. mp3 file of 430kb. Plays absolutely fine.
Both at 44.1khz.
What reason for an audio MP3 file not playing
