The audio player embedded into recorded-jams pages of the website doesn't seem to work on Firefox (tested version 37.0.2 and 31.5 on different systems). The player displays correctly, I click on the play icon, the progress bar starts moving, data are being downloaded, but I can't hear any sound; the duration time is frequently updated, until the progress bar reaches the end, download stops, and the final duration displayed is way less than what it should be (e.g. 3 minutes, instead of 1 hour).
Is this a bug or a problem on my side?
Downloading the .m4a file works ok (though I found the overall volume level quite low)
