As suggested by Ferdi : I've tried to create a re-encoded film formatted "mp4" instead of "avi" : now I have both sound and image in re-encoded film 🙂
Thanks everybody for your help 🙂

Although the avi container supports the X265 codec this is merely
because it is not really critical about what Codec is used, By design
avi has many limitations for modern Codecs. You cannot use B-frames for
example and many of the other advantages of the HEVC format cannot be
used in this ancient container format. Remember the avi container dates
from the early 1990's when X265, X264 or any other modern codec did not
exist yet! Use avi for the Codecs of that era and youĺl be fine! (xvid,
divx etc.)

So please use a modern container format for X265 encoded video, such as
MP4 or MKV. They are much more efficient and allow full use of all X265
