The VideoLAN Forums

I know this question has come up BUT what I am looking to do is play both the audio from a movie file and and mp3 at same time.

when i use the 'play another media synchronously' it just adds a new audio track that plays separate from the video's audio.

im simply looking to add audio on top of whats already there (aside from editing/merging files).

Thanks.

Yes, this is normal, VLC cannot play two audio tracks at the same time.
