Windows 7 is much better about sleeping than it's forerunners. Unfortuantely, I still find one common case where it does not sleep when it should: When there is an open audio stream. Many applications can leave an open audio stream. The most common for me is just having an open browser window with a Flash movie in it. The movie can be paused or finished, but the audio stream remains open for as long as the page is still up. You can verify stuation this using the following command response my machine gives follows)... ==== C:\Windows\system32>powercfg -REQUESTS DISPLAY: None. SYSTEM: [DRIVER] SoundMAX Integrated Digital HD Audio (HDAUDIO\FUNC_01&VEN_11D4&DEV_989B &SUBSYS_10438334&REV_1003\4&18dbcfae&0&0001) An audio stream is currently in use. AWAYMODE: None. ==== How can I make my Win7 computer follow the normal inactivity sleep timeout even if there is an open audio stream? NOTE: I am looking for a way to do this using native Win7 functionality and I would rather not install a 3rd party code. Thanks! -josh

Hi Josh, Have you tried this? MicroSoft TechNet "Finally went to: Control Panel\Network and Internet\Network and Sharing Center\Advanced sharing settings And under media streaming - blocked all - and that did the trick! I don't know if there's another way to allow streaming and enable sleeping, but for now, beats running all night long after waking for a time update etc... :-)" http://social.technet.microsoft.com/Forums/en/w7itproui/thread/bce158e2-d057-4761-b715-5f68b8002fc2 Regards, Patricia

bj, There's a discussion of this problem here: http://www.soundgraph.com/forums/showthread.php?t=884 which makes it sound like as it's specific to certain drivers. You might want to see if you have any options along those lines to select a driver compatible with sleep mode. At least until a researcher (hopefully) comes along with a more permanent solution. David

Sorry...I didn't see Patricia's post...perhaps she's found the solution already.
Question clarification by bigjosh on Mon 4 Jan 2010 - 7:24 pm UTC:
Patricia: I had checked the streaming setting and it is off. This has to do with Flash having an open audio stream on the local machine and that open stream causing the sound card to register a power request. Reading Davesarokin's link, I saw a reference to the -REQUESTSOVERIDE parameter to the POWERCFG command. A couple of google searches turned up this this document... http://download.microsoft.com/download/7/E/7/7E7662CF-CBEA-470B-A97E-CE7CE0D98DC2/AvailabilityRequests.docx ... describing how to use this to tell Windows to ignore a power request source. This is exactly what I was looking for. So, I entered... powercfg -REQUESTSOVERRIDE DRIVER "SoundMAX Integrated Digital HD Audio" SYSTEM ...and now my machine sleeps even with a video running! By entering the appropriate REQUESTOVERRIDE command, you should be able to tell your machine to sleep despite requests from *any* program, driver, or device that is trying to keep it awake. Thanks! -josh

I ultimately found the answer myself, but could not have done it without the helpful comments. Thanks uClue!
