My powertop reports this for the two audio codec components.

4.85 W    100.0%                      Device         Audio codec hwC0D3: Intel
4.85 W    100.0%                      Device         Audio codec hwC0D0: Realtek

I think 10 W for audio is too high. Can somebody please suggest me a way to reduce the power consumption?

It'd be nice if someone could educate me on this, I have an idea about codecs in general but I have no clue about their internals? Why is it that these two components keep running always even when I am not listening to audio?
