Sample ODP

- Insert an MP3 file in a presentation, eg. one from [1], or open attached ODP, which contains one.
- Save it as PPTX, and reload.

=> No sign of the MP3 in the presentation (the archive doesn't contain the MP3 file).

In PPT embedding media isn't possible, so this isn't relevant there.

Observed using LO 6.4.0.0.alpha0+ (58ef8c188b6bb2ed307f5e825cc7e475c33d0c33), 4.0.0.3 / Windows 7.

Here's how PowerPoint saves a file with embedded MP3.
Comment 2 Aron Budea 2019-06-30 14:22:34 UTC 
Actually, the same happens if the MP3 is linked, let's include that issue here.

On Win10 with master sources updated 3 days ago, I could reproduce this.

I noticed this log on console:
warn:sd.eppt:3468:6236:sd/source/filter/eppt/pptx-epptooxml.cxx:324: unknown shape not handled: com.sun.star.drawing.MediaShape
Comment 4 norman 2020-09-03 10:12:47 UTC 
I can confirm that this bug still exists in LO versions 6.4.6 and 7.0.1.2.
The audio appears to be embedded when first placed on a slide and tested while LO still running. However reopening the pptx file reveals that the audio is no longer embedded.

Can the bug be escalated as it has a new importance with educational institutions going online?

norman: no need to repeat yourself.
This bug is not a priority since:
- it's not a crash
- not a regression
- you may use odp (the native format for LO) as a workaround
