SUMMARY
***
There appear a number of significant issues with the playback of embedded audio in pdf files and the appearance and functionality of the PLAY widget.

***

STEPS TO REPRODUCE

1. Download the pdf "Sanskrit Pronunciation Guide" at https://www.theosociety.org/pasadena/sk-pron/skpro_01.pdf.

2. Open the pdf file.

EXPECTED RESULT: Audio playback should only start when the user presses the PLAY button.
ACTUAL RESULT: Audio starts automatically.

3. While the audio is playing, scroll downwards so that the PLAY widget disappears from the viewport.

EXPECTED RESULT: Audio playback should continue normally. It should only stop when the user presses STOP/PAUSE.
ACTUAL RESULT: Audio stops playing and the PLAY widget changes appearance to display "Play Audio".

4. The Play controls are rudimentary;  there is a double chevron to the right of these but this appears to be non-functional;

EXPECTED RESULT: The PLAY widget should be larger; there should be some way to drag playback forward and backwards to any position in time.
