Hi,
here is a feature request about the LaTeX export.
With ~(setq org-latex-listings t)~, code blocks such as:
┌────
│ #+BEGIN_SRC ⟨language⟩ :exports code
│ ...
│ #+END_SRC
└────
are exported to LaTeX into:
┌────
│ \lstset{language=⟨language⟩,label= ,caption= ,captionpos=b,numbers=none}
│ \begin{lstlisting}
│ ...
│ \end{lstlisting}
└────
But the:
┌────
│ \lstset{language=⟨language⟩,label= ,caption= ,captionpos=b,numbers=none}
└────
systematically added before each of the ~lstlisting~ LaTeX environments
is not always desirable and let me explain why.
Sometimes, you want the ~listings~ package to have some global settings
that are overridden by this ~\lstset{...}~ added by Org. Typically, you
may define some dialects ⟨dialect1⟩, ..., ⟨dialectN⟩ of a given
⟨language⟩ and you want to load them in addition to the (main)
⟨language⟩. This can be done by the following global setting:
┌────
│ \lstset{
│ language=⟨language⟩,
│ alsolanguage=[⟨dialect1⟩]⟨language⟩,
│ ...
│ alsolanguage=[⟨dialectN⟩]⟨language⟩,
│ }
└────
Unfortunately, it is overridden by each ~\lstset{...}~ added by Org.
So would it be possible to provide an option that prevents Org to add
these systematic:
┌────
│ \lstset{language=⟨language⟩,label= ,caption= ,captionpos=b,numbers=none}
└────
Thanks!

Confirmed.
Is there a way to apply \lstset locally for the environment?

It is enough to put it in a group:
┌────
│ \bgroup
│ \lstset{...}
│ \begin{lstlisting}
│ ...
│ \end{lstlisting}
│ \egroup
└────
Otherwise, all the options specified by `\lstset` can be applied as an
option of the `lstlisting` environment:
┌────
│ \begin{lstlisting}[language=⟨language⟩,...]
└────

This should be the safest and the least verbose.
I implemented the suggestion in the attached patch.
Let me know if it works for you.
