Only unofficial (beta) drivers are released weekly or even more often.
Official drivers are only updated a few times per year on the realtek website. They provide basic support for your soundcard and should work just fine.
Your motherboard manufacturer is probably releasing audio drivers a bit more often and they usually add some additional stuff like more sound effects. It’s your decision if you want or need them.
Note however that using other sound effects along with DPS may result in a degradation or distortion of sound. So you should make sure to use only one at any given time.
Btw microsoft is also releasing realtek drivers from time to time.
Still most driver updates just support new soundcards or fix small bugs for specific models and so may have no advantage over older ones for you. If one works fine staying with it will probably not cause any problems.
