1/2 second delay in audio start when headphones are connected through aux

[Fayiz159]

When headphones are connected to my laptop, there is a 1-2 second delay in when the audio starts compared to when a video starts, or when playing music. The audio is in sync, but is silent for the first couple of seconds. 

For example, I'll play a video, and 2 seconds later the audio will turn on, (but as stated, it's in sync). Another example is when I play a song, I'll miss the first couple of seconds of the song. 

I have updated all the audio drivers on the computer and nothing has helped thus far. 

Also tried the following steps below so far none helped:

Go to Windows Device Manager > Sound, video and game controllers section.
In the list of audio device drivers, look for Realtek High definition Audio. This is the device driver for BeatsAudio (a little bit sneaky, wouldn’t you say?).
Right-click and select Disable. The downward arrow displays on this driver, indicating it is disabled. (NOTE: At this point, you won’t be able to play any music files.)
Right-click and select Update Driver Software.
Select Browse my computer for driver software.
Select Let me pick from a list of device drivers on my computer.
You should see a window that says Select the device driver you want to install for this hardware. NOTE: If you see a window that says something like This is the best driver for this device, exit the window and repeat steps 4, 5, and 6.
In the Model box, highlight High Definition Audio Device (this is the substitute audio device driver) and click Next.
At the Update Driver Warning window, click Yes. You should see a confirmation window with High Definition Audio Device displayed. Click Close.
In the list of audio device drivers in the Sound, video and game controllers section, you’ll notice that the High Definition Audio Device now displays instead of Realtek High definition Audio.
At the prompt to reboot, click Yes.

If the issue still persists try the steps recommended below.

Is the loudness equalization off? If not, please:
Right, click the speaker icon
select 'Playback Devices'. 
Highlight the default device
Click Properties
Click Enhancements tab
Next to 'Loudness Equalization' take out the check mark in the box.
Click Apply
Click OK

If the issue still persists uninstall the audio driver from device manager and install the drivers using HP recovery manager.

thank you in advance.

Got a solution from community itself after searching sometime:

https://h30434.www3.hp.com/t5/Notebook-Audio/System-Sound-Delay/td-p/6224970

New temporary solution that works with Realtek drivers.

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.
