Hi Sigotnin,
I'm glad to see that you're trying to optimize your sound setup. The bit depth is an important part of sound quality, and it can be tricky to figure out the best settings for your DAW device. Fortunately, 16-bit seems to be the default for most DAWs, so you shouldn't have to worry about changing the bit depth. Just make sure to save your work in 16-bit and you should be good to go!
