On my LibreOffice 3.5.1 (installed over ppa) on Ubuntu 10.04 64 bit I have the following problem with impress:
If I add a custom animation to an object with sound, the custom animation works, but no sound is to hear.
Sounds added to slide transitions work.
Problem stays in 18.104.22.168
Thanks for bugreport
Please, verify if in last version of LibreOffice still reproducible
(3.5.4 or more new)
Problem still exists in 22.214.171.124.
Thanks for additional testing
in 3.5.4 on Fedora 64 bit sound in animation works. ogg format used.
May be I do something wrong. Please, attach presentation that demonstrates this problem.
mp3 format not works. But problem is not in LO, but in Fedora. Ability of playing this format is removed from Fedora and many other Linux distros. It is too old.
No attachment to test?
