HP ENVY Curved All-in-One PC 34-b0xx HDMI Audio Issues

[Niall05]

So i have noticed that when i plug in a HDMI into the HDMI input at the back of my desktop and then use the HP Display Control to get me to the HDMI Input, once on the HDMi display there is no sound coming through despite when on the Windows screen and HDMI is turned off, there being sound as normal, 

any ideas how to resolve this issue?

HI I dont think you quite understand, 

My computer is a desktop tht also acts as a moniter when it goes to HDMI mode, when i am using my desktop as a computer the sound is perfect, when i switch t to be a monitor for the HDMI Input then there is no sound. 

this issue started on the 9th November, when in contact via a telephone call, they said it was due to a microsoft update that occured on that date which has cause the issue, however when compleating a System Recovery as instructed to get a older, fully working file, this apparently resolved the issue before it then reverting back to no Sound when in the HDMi mode, despite sound coming out when on the computer setting. I have also gone back and installed an older version of realtec sound software to try and resolve this issues. 

the headphne port works as normal, nd the sound bar which is part of the all in one desktop also works when on the computer setting but not when it is switched to the HDMI Input.

@Niall05, Thanks for your prompt response and time.

I appriciate your efforts for writing back to us.

Did you try a different HDMI cable and check the settings in the Control Panel / Sound to assure that settings are correct?

As you mentioned after reset the issue reoccurred again.

Uninstall the audio driver from your PC and install the previous version of audio drivers and check if it helps.

Update the audio drivers using this link. Click Here

Also, to fix audio issues in Windows 10 by setting the default device option, just open Start and enter Sound. Now open the appropriate result and click on the Playback tab. Here find the suitable audio device and Set Default.

Hope this helps!

Take Care! 🙂
