AMD Radeon RX 550 4GB Dell Low Profile HDMI Audio Not Working On Roku 720p TV?

 

Does anyone know why I cannot get the sound to work on rx 550 dell low profile on windows 11?  It says not plugged in, in mmsys.cpl.

 

I installed a newer & older audio driver & display driver & it doesn't work on my this 32" Roku 720p tv nor does it work on a Hisense 43A6H 4k 43" tv.

 

It worked on two older Element TVs though so why does it say not plugged in on these two new TVs on this RX 550 only?

 

Thanks

It wouldn't have anything to do with your audio driver, it would be the GPU driver that powers the audio over HDMI. 

 

A quick search suggests the Realtek driver is interfering with the AMD driver.

Okay the guide is on a Windows 7 PC, should it all still apply to Windows 11?

It's definitely possible. 

 

just uninstall your Realtek audio driver and then reinstall your GPU driver. Might not fix your issue, but easy thing to try.
