Windows 10: HDMI Audio playback device not recognised

Hi everyone

The issue i have is that when i connect my laptop to my tv via HDMI i cannot get any audio, the video works like it should. It constantly says "not plugged in" and is greyed out in playback devices. The issue is only when running windows 10, when i boot into Ubuntu on the same machine the HDMI connection works perfectly so i figured it cant be a hardware problem....

I have tried installing AMD legacy drivers, updating my graphic and audio drivers through windows updating and searching the web for older drivers as it has worked in the past. I have also performed a reset in win 10 because had been playing around with scheduled tasks to try and improve boot time on my ageing machine.

Also tried starting the computer with the HDMI cord already plugged in and the TV on just in case it was some sort of issue recognizing it getting plugged in. Have also tried deleting drivers and restarting with the cord still attached.

My Laptop is a Compaq Presario CQ62 402AU
CPU - AMD Athlon II P360
Graphics card - Radeon HD 4200 series

I apologize in advance if i have posted in the wrong section, i have been searching for a solution for a week now and cant seem to find anything that fixes my problem

Thanks in advance for any help

:)

 

Sound

I have managed to sort the issue out. In the Playback devices I had Realtel HDMI Output as the Default Device and when changed it to Digital Audio (HDMI) as the Default Device the sound worked. Thank you for all your help

 

No sound from hdmi output windows 10

My issue, as I later figured out was that my Playback Devices where no longer automatically switching between my laptop Realtek and my my AMD High Definition Audio Device. (You may have Realtek or other HDMI Audio devices instead of AMD). So I change playback
defaults every time I use the HDMI.

Also make sure prior to using you HDMI that you switch your AV on your remote.

I switch my AV to HDMI 1 on the TV Imput Select which may be different on your television. My television is an old plasma set. But it's still beautiful High Definition 1080p.

BTW. Playback Devices are located in your sound. Right click on sound located on the Taskbar Select Playback Devices and right click the selection showing a television and select Set Default Device. Change your Default back to Speaker when done using HDMI.

Hope this helps you out.
