Hello @
facr73,
Currently, Recording in Motion Live does not automatically play Background Music.
If you have any needs in this regard, please go to Feedback Tracker to submit your thoughts.
Background Music and Lip-sync are two different functions. If you want to add Lip-sync, my suggestion is not to add the audio file to the Timeline of Background Music, but to the voice clip of the character.
As long as the file format is wav or mp3, the voice clip on the character should be able to be played smoothly and lip-sync to the character during recording. If not, please go to Technical Support so that we can check the question attentively.
