Topic: Ideal Sample rate for normal computer use.

Hi, my is the following. After running ableton live the fireface sample rate setting changes to either 48000 or 82000, and stays there after i finish working with my DAW, is it better/more efficient to switch it back to 44100 for normal computer use? Does it make any difference if for example I am listening to a cd and the sample rate setting is at 48000 or even 82000? What about the buffer size? is it better/more efficient to have a lower buffer size when I am not using my DAW?

Thank you
