Description Aron Budea 2025-11-26 18:20:26 UTC 
- Create a new presentation,
- On the Transitions sidebar, pick an entry from the Sound dropdown, apart from the first three entries, eg. "apert" (needs galleries component),
- Play slideshow.

=> No sound is heard.

Note: if you don't have galleries (eg. bibisect build), but have an older build installed separately that does, create and save the presentation there, and open it in the other build. As reported in bug 67544, media is referenced separately, and not saved into ODP, but as long as the location stays the same, that isn't a problem.

Observed using LO 26.2.0.0.alpha1+ (2025-11-22) / Windows.

This started with the following commit in 26.2:

"tdf#62408 tdf#159292 Impress: Introduce Microsoft Media Foundation APIs"

Since this is a Windows-specific change, likely the issue is Windows-specific.
