Is there a way to render sound and video in the sequence editor in blender?
No. You can output the video stream and then the audio stream separately, but then you would have to join them in a separate application. Blender cannot render both streams together.

BTW: Has anyone make sound work in Blender for Linux? In my blender 2.36, 2.37a and 2.40alpha1 for linux sound imports but console claims “no audio device found”.
Audio devices work perfectly on every sequencing application outside blender; such as Audacity.
Any ideas?
