Tumblr has updated the audio player again.
Please note that tumblr has updated the audio player in audio posts again without much notice. This leaves theme makers as a disadvantage as they will have to reconfigure their past codes to work with the new style.
If you are experiencing trouble with this, please be patient with theme makers. They may not be aware of this problem so feel free to link to them this notice. With some themes it may not be a quick fix so take a deep breath and try and be supportive of theme makers as they have to deal with this annoyance instead of pointing fingers and sending demanding messages.
