During descent into ZZZ1 we leveled at 6;000 feet and as the power increased we noticed a dirty sock smell that lasted for approximately 1 to 2 minutes. When the power reduced again as the descent continued the odor dissipated. The flight attendants noticed it in both the forward and aft cabin in flight. Once at the gate when the APU bleed was selected the odor returned although it was much less noticeable. Possible problem with the APU causing some sort of contamination in the packs. This has been a continuing issue that the company has been working to correct. Apparently more needs to be done to prevent these types of fume exposures to both passengers and crew.
A320 Captain reported a temporary fumes event of 'dirty socks' smell during landing approach. Odor returned at gate arrival.
