Have you run diagnostics?
Tap the ESC key after powering on. . Tap it once a second after you see the LEDs on the keyboard flash. When you see the startup menu, press F2 to run diagnostics.

HP releases newer UEFI diagnostics periodically.
When you select F2 during boot you are requesting UEFI diagnostics.
There is an updated diagnostics package Click Here
Look for the phrase 'issues outside the OS',
Expand the '+' symbol and click the DOWNLOAD button.

If there is a speaker test, and there is no sound, then return the laptop for warranty service

If the audio works in UEFI test then the problem is windows

Are you getting any sound to speakers or headphones?
Here is Microsoft's general help for audio problems

Does the device manager show any problems like a red "X" ?.

If connected directly to the TV then check your audio mixer.

Bring up the sound mixer and set the audio to the graphics device if using HDMI or to the speaker system.

for example.

Let me know what you find out.
