No audio in video render

I have just started using blender’s nodes. I want to import a video (in .mov format) then apply a few filters and output an avi file.

I have no problems importing the movie, setting up the nodes and getting it to render however the exported video has no sound.

Do I have to tell blender to include the sound with the render or import the sound separately (or both) and how can I do that.

thanks for any help you can give

I could be wrong but I believe you have to add the Audio bake in using the VSE: http://wiki.blender.org/index.php/Manual/Audio_Sequences

I cant find a way to render video with audio.

Where is the audio bake ?

Sorry, that was a typo on my part. I mean “add audio back”. You have to load the audio as a new strip in the VSE. You also have to set your Render panel to render with FFMPEG.
