In order to obtain divalent sulfur oxide from hydrochloric acid, it is necessary to react hydrochloric acid with any salt of sulfuric acid. When acid and salt interact, salt is formed, sulfur oxide is tetravalent and water is released. For an example of such a reaction, take the sodium sulfate salt. Then the chemical equation of the reaction will look like this:
Na2SO3 + HCl = NaCl + SO2 + H2O
as a result of this reaction, sodium chloride salt, tetravalent sulfur oxide is formed and water is released.
