audio output delay when I connect headphones

[TBARDI]

Hello everyone, I have an HP Pavillion 15cs0xxx i7 eighth generation and B&O audio.
It often happens to me that, both from Youtube and from the mp3 player, when I start a video or a song with the headphones attached (or any other device connected to the headphone output), the audio in the headphones arrives with a slight delay. It always arrives in sync but simply after the beginning of the video or track. Always a second two at most.
It happens to me more often if I haven't used youtube for a long time despite having the tab open, "when I get back", I click play and the audio comes later.
If, on the same video, I press play and pause repeatedly (after the first delay), everything works as it should.
What could it be? Does it happen to someone else? is it solvable?
Thank you so much!

@TBARDI,

Welcome to the HP Support Community!

I reviewed your post and I understand that there is a delay on the headphone when you play videos online or from the computer.

Don’t worry, I assure you I will try my best to get this sorted.

I recommend you follow the below steps and check if it helps.

To begin, right-click on the audio icon in the taskbar and select “Playback Devices”:

Double-click on your primary audio device to bring up the speaker/headphones properties dialog, and navigate to the “Advanced” tab:

At the bottom of this dialog, locate the option labelled “Allow hardware acceleration of audio with this device” and uncheck this option. By default, this will be selected, causing the problems described above. Unselect this option and press “OK” to save changes.

Let me know how it goes and you have a great day!

@TBARDI,

I recommend you follow the below steps and check if it helps.

The audio troubleshooter might be able to fix audio problems automatically.

To run the troubleshooter

1. In the search box on the taskbar, type audio troubleshooter, select Fix and find problems with playing sound from the results, then select Next.
2. Select the device you want to troubleshoot and then continue through the troubleshooter. 

You can also launch the troubleshooter from audio Settings. Select Start  > Settings > System  > Sound  > Troubleshoot.

If running the troubleshooter doesn't help, continue to the next tip.

Verify that all Windows Updates are installed

To check for updates

1. Select Start  > Settings  > Update & Security  > Windows Update   > Check for updates.
2. Do one of the following:
   • If the status says "You're up to date, go to the next tip. 
   • If the status says "Updates are available," select Install now. 
3.  Select the updates you want to install, then select Install.
4.  Restart your PC and see if your sound is working properly.
