Realtek HD Audio - No Sound After Idle For 5 seconds

Hello there.

Recently I installed Harman Kardon's Soundsticks unto my PC.
The problem I'm going to describe started from the moment I installed the new Soundsticks.

What happens, is after some time when I don't touch my PC (5 mins? not sure), sounds will cease working, unless I "wake" it back up by trying to play sounds. Then, it takes about 5 seconds for the sound to come back up.

This is extremely annoying - and frustrating. I had a similar problem with my Keyboard, where after 10 seconds if not touching it - it "turned itself off", and when I reclicked it, it continued working again. I fixed that problem by disabling power management for the keyboard.

Sadly! I cannot find, anywhere, any option in device manager or anywhere else, an option to disable Power Management, which I suspect is causing my speakers to not work after I leave my PC alone for a bit.

I'm using my PC for alerts sometimes, which is extremely annoying, because since the PC was idle, the alert sound will not pop off because of this annoying bug.

Please help me!
 
Hi,

Please do try changing this settings from Power Options that may help.
- Open Power Options then click on Change Plan Settings then Change Advanced Power Settings.
- Expand Hard Disk then set Turn off Hard disk after to NEVER.
- Expand Sleep and set Allow hyrbid sleep to OFF.
- Set Hibernate after to NEVER.
- Do also set Sleep Mode to Never.
- Click Apply and OK then test it again and see if the same problem will persist or not.
- If all these will not work, last option would be to reinstall Windows.
- If it doesn't work please do also try to uninstall/reinstall the Sound card driver.
- Go to Device Manager and uninstall the Sound card driver.
- Once uninstalled download and install the latest driver from the manufacturer site.
- Reboot the PC again once the latest driver has been installed.
- If all these will not work I would also suggest doing a clean install Windows.

Thank you for your tips.

I tried all those tips - except for uninstalling and reinstalling windows clean. I really do not think that this issue justifies a clean install of windows from 0... Seems a bit of an overstretch. Especially since I believe, and maybe someone knows, whether there is a registry entry that allows to turn off power management for Harman Kardon or the Realtek audio files.

A bit late in the game here but hopefully this will help anyone with the same issue. This is for NVIDIA but the registry hack will work with most. After putting up with this annoying issue for 6 months, doing this step worked for me.

Find HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class{4d36e96c-e325-11ce-bfc1-08002be10318}\xxxx\PowerSettings

Where 'xxxx' is one of keys which contains DriverDesc value 'Nvidia High Definition Audio'. (Mine was '0000')

Note: There may be multiple ones containing PowerSettings, for example 'Realtek High Definition Audio'. Do not change those.

Within PowerSettings, You'll find there are three binary values and set them to:

ConservationIdleTime = ff ff ff ff;

IdlePowerState = 00 00 00 00;

PerformanceIdleTime = ff ff ff ff.

Default values are all 00 00 00 00 which disables power settings, but driver somehow overrides it with 0a 00 00 00 which is 10 seconds (0x0a = 10) and is by default in driver.

Reboot.

Hi, I'm having the exact same issue and tried all the above, inlcuding this registry change for the realtk HD audio entry but it hasn't helped unfortunately.

Its becoming a real nuisance and it's been this way with two PCs now.
