Welcome to HP Forums,
This is a great place to get support, find answers and tips,
Thank you for posting your query, I'll be more than glad to help you out :)
I see that sound delays when connected to external headphones:
Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:
- Did this happen after a recent window or software update?
- When was the last time it worked fine?
- Have you made any hardware/software changes?
- Are you using the 3.5mm jack or USB powered headphones?
While you respond to that, I recommend you to perform the following steps to isolate the issue and arrive at a fix:
Ensure that your headphones are connected to the right jack plug (the green one/Line-out).
Make sure the device is recognized by the computer
Connect the device to the computer.
From the Start screen, type sound to open the Search bar, then select Sound from the search results.
Click the Playback tab in the Sound window.
Right-click an empty area of the Sound window.
Click Show Disabled Devices and Show Disconnected Devices.
If the device is listed as "Currently unavailable" or "Not plugged in," disconnect it, then reconnect it to the port. If the device is still not detected, refer to the Check the headphones or headset section of this article to check the device and connections.
Test the device by sending a signal from the sound source. For example, play a .mp3 music file to test the headphones or speak into the microphone to test a headset.
If it's not detected, then either your drivers are missing or the headphone jack itself has failed.
It's not the drivers, considering the speakers are fine, so we can rule that out,
If you have the headphone showing under playback devices, Then all you need to do is set them as the default and that should fix your problem.
If the issue persists, run a test on the headset: Click here for details (look under Testing the headphones using HP PC Hardware Diagnostics (UEFI) - The document is for Windows 8, however, it applies to Windows 10 as well.
Hope this helps! Keep me posted for further assistance.
