Hi Atick,
So, it shows the proper sample time now but you have not stated what you did to do so. The only thing that I noticed is that the audio element has been moved up to the top, under a new heading, "CONTENT," along with the AUDIO LENGTH setting now removed. My client shall be adding more
original content so I need to be able to do this consistently. I don't wish to submit a support ticket
every time I need to add a new song to the list.

Additionally, you failed to address the secondary issue; specifically, setting the initial audio level to whatever level we desire. I've seen other DEV's audio add-ons with both of these settings as elements of the component. If this add-on is to be SPPB's "advanced audio" element then these are types of settings that should be the "advanced" aspect over the basic add-on element, "audio."
Regards.
