Not sure if this is a bug so I’ll create in Misc …
I can’t seem to get an animation with sound going. I add an audio file into its own track (an Ogg vorbis file). It seems to appear on the track but upon playback, I get no audio. This is on Fedora Linux
We currently don’t support the .ogg format. You should convert it to a .wav with a program such as Audacity before importing. There have also been some reports of issues with sound importing on linux, so there is a chance that even that may not work correctly. Try using a wav and let us know if you are still experiencing issues.
