How to soundcard from entering D3
I have an issue I've been trying desperately to figure out for the last two months. I can't find the power management options to stop my sound card from entering D3 while the computer is running. Basically, if no sound is playing for a period of time, approximately five minutes, the sound card switches from D0 to D3 and shuts down. Unfortunately, if any speakers are plugged in they start to hum. I can observe the switch in the "Power data" section of the driver details so I know it is the problem. Here is the contents of "Power data" if they help at all.
Current power state: D0 Power capabilities: 00000089 PDCAP_D0_SUPPORTED PDCAP_D3_SUPPORTED PDCAP_WAKE_FROM_D3_SUPPORTED Power state mappings: S0 -> D0 S1 -> Unspecified S2 -> Unspecified S3 -> D3 S4 -> D3 S5 -> D3

HP Pavilion Laptop 2714ca
Built in sound card: Conexant High Definition SmartAudio 221
The laptop came loaded with Windows Vista originally but I wiped it the next day and used Windows XP for the past two years. No issues. Upgraded to Windows 7 Pro about two months ago, all of the drivers work fine except the sound card going to sleep because of the power management settings.
