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.
