Audio is not played several second after resuming video

[JackShmitt · Accepted solution]

I had the same issue with my laptop. Here is how I fixed it. Hp seems to not have its act together when it comes to audio

 It was supposedly due to a power setting that caused a delay. (https://h30434.www3.hp.com/t5/Notebook-Audio/System-Sound-Delay/m-p/6508198#M91186)

New temporary solution that works with Realtek drivers.

You have to go into change the registry, to fix this. Go to start type "run" . In run diaglog box enter "regedit".

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 'Realtek High Definition Audio'.

Note: There may be multiple ones containing PowerSettings,

for example 'Nvidia High Definition Audio'.

You'll find there three binary values and set them:

• 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.

Problem shouldn't occur again after restart (or I haven't noticed).

This is not solution to problem,

it only prevents audio hardware going idle,

but I don't see any impact on energy consumption.

It only worked temporarily for me. The problem still persists. And this is a new computer.

Thank you very much JackShmitt, it seems it works!!!

It is actually a DPC latancy issue.

We need Hp, Microsoft and the driver makers to fix this issue.
