Bug ID: 169438
Summary: FILESAVE: PPT -> PPTX improper export of audio in
animations.
Product: LibreOffice
Version: 26.2.0.0 alpha0+ master
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Impress
Assignee: [email protected]
Reporter: [email protected]
Description:
Open the attached file and save it as PPTX. Open the resulting file in
PowerPoint. PowerPoint fails to open the file.
Both officeotron and OOXML validator doesn't give any errors.
If we initially save the file in PowerPoint and roundtrip it in LO, it opens
without any problem in PowerPoint.
The issue seems to be with additional export of audio in animations.
If we unzip the pptx file saved in LO and look at the formatted slide1.xml, in
animations we have the below xml
```
<p:audio isNarration="0">
<p:cMediaNode showWhenStopped="1">
<p:cTn/>
<p:tgtEl>
<p:sndTgt r:embed="rId1" name="wind.wav"/>
</p:tgtEl>
</p:cMediaNode>
</p:audio>
```
This audio element is not attached to any valid node. If we remove this part
from the XML and rezip it, the resulting file opens without any problem in
PowerPoint
Steps to Reproduce:
1.Save the attached in as PPTX
2.Open the resulting file in PowerPoint
3.PowerPoint fails to open the file
Actual Results:
PowerPoint opens the file without any issues
Expected Results:
PowerPoint fails to open the file
Reproducible: Always
User Profile Reset: Yes
