Description Luke 2019-03-06 20:47:18 UTC 
This is a follow up to Bug 44223 which added sound to slide transitions. This is about the missing sound in slide animations. 

Steps to reproduce:
1. Open attachment 145684 [details]
2. Start slideshow

Expected results:
1. Both the animation sound,"wind.wav" and the transition sound, Applause are played.

Actual results:
1. Only the applause transition is played
Comment 1 Luke 2019-03-06 20:51:11 UTC 
Note: attachment 145685 [details] shows that the PPT format is correctly imported. Both sounds play.
Comment 2 Mark Hung 2019-03-14 12:01:14 UTC 
I can hear the wind.wav, although it comes out much later. ( I waited 4 or 5 seconds after the heart appears. I didn't check why it started so late. ) Can you check again?
Comment 3 Luke 2019-03-14 17:36:00 UTC 
Yes, if you wait more than 5 seconds after the animation shows, the sound will play. The sound should play concurrently with the animation like the PPT file. 

If you preview the sound effect in Impress, no sound will play. The sound effect in the PPT file will correctly preview.
Format->Animation->Effect Options->Preview

If you save the file and open in Powerpoint, the sound also plays 5 seconds after the animation has completed. If you check the animation properties, it has no sound effect associated with it.
Comment 4 Mark Hung 2019-03-16 12:29:56 UTC 
Modify the title because the issue happened without saving. Also try to avoid mixing any FILESAVE and FILEOPEN issue.

Unfortunately, the export is still not working correctly. Nor can you preview PPTX sound effects. I filed the export bug as Bug 124230. How do you want to handle the audio preview bug?
