Hi,

  could you explain, why the power-save function causes this behaviour? Can we do something else than turning off the power-save codec settings to avoid such noises? I have this question because it's
really easy to disable something, but I feel that the culprit of the noises might be just the wrong codec settings. I guess that you have probably full documentation for the codec and probably for the
hardware, so it might be nice to find the real culprit.

			Thank you,
				Jaroslav
