Hp monitor speakers not working (HP - 25" 1920x1080 60hz)

[TomC131]

With this monitor, I have not been able to get the audio to work. The information on this monitor is very limited on the internet and I have not been able to find someone else with this problem.

The number of the product is: HSD-0011-Q

Serial number: [personal info removed]

When I connected my pc to the monitor using several HDMI cable, the display works but the audio does not. My pc does not have a VGA port so that is not an option. 
 

I tried plugging an audio cable into my pc and the monitor but it didn’t work. The monitor audio comes up as an audio device but no sound comes out of the monitor when I play audio. 
 

With headphones connected to my pc, the audio is fine.

When troubleshooting the audio of the monitor, I’m told there is nothing wrong with the audio. 

Does anyone else have this problem - is my audio cable the problem or are the speakers broken?

Are you sure it has speakers ? I can't find it specs.

>>>> My pc does not have a VGA port so that is not an option. 

VGA does not carry sound therefore you can't use VGA alone anyway.

If it did have speakers. Can you see it under sound ?

   (a) If yes, you have to enable it,

   (b) If NO, you need its drivers - I can't find its specs therefor I don't know it has driver or not.

Again, I need to know what is it ?

Regards.
