Hi All,

I have code written for audio for Power state Do and D3,
But i see the s0 and s3 is taking more time .

I run the tool Windows Assessment Console with individual option selecting
standby .
I got the warnings 3 and has a 8 issues .

8 issues states are related to Process system uses the CPU for 1.0 seconds
during standby-Resume Post On/Off.

Any help it will be great.

Looking forward from your thought on this issues related to power dwell…

Hi All,

I am requesting to help on these i have more information , i have codec
Driver and Graphic driver both are installed in my Pc
codec driver is getting the OS call 9which i am not sure) causing codec
driver to have more delay during sleep mode.

The expected behavior is should consum less time .123 sec (not .583 sec)
as seen from windows assessment console.

Kindly help to ensure the codec driver consumes less time stamping during
sleep mode

kumar

I don’t understand your situation. Why is your codec operating at all
if the computer is in “sleep” mode?

If you are getting cycles, they will certainly be at a reduced clock
rate. It shouldn’t be surprising that things take longer.
