The `comint-process-echoes' variable is buffer-local, so you need to set
it in the shell buffer. Something like this should work:

    (defun my-init-shell-mode ()
      (setq comint-process-echoes t))

    (with-eval-after-load 'shell
      (add-hook 'shell-mode-hook #'my-init-shell-mode))

Hope that helps
