I've been using this great plugin for at least 6 months for a page to provide rehearsal tracks players for a chorus. It worked flawlessly across every device, OS and browser I could test it on. But then....
I just upgraded to 1.8.3 (from 1.7.3?) and immediately had performance issues with the playlist player. Seemed to work fine in Chrome, but unpredictable performance in IE and Firefox, with the playlist sometimes not loading into the player, or if it did, clicking a song title would say "connecting" but never going beyond that.
So, I just upgraded to 1.8.4, and now smooth again in the big 3 browsers on my PC, but very sluggish behavior and no sound on my iPhone 4S (iOS 6.1.3).
Here's the chorus site: http://fgmea.org/abcdefg
Due to a licensing agreement, I'll have to take this down in the next week or so since we are finished using it for the year.
Same issues here with the single players: http://rodmusic.com/listen
I'm going to downgrade mp3-jplayer on this site to 1.7.3 so that visitors don't encounter problems.
Update: Further experimentation with my iPhone shows it works fine in Chrome, but not in Safari: First track plays okay, but after switch tracks a couple times sound is gone. After that, no sound in Chrome unless I quit it and restart.
