Sorry if this repeating a question but I have tried a few methods to resolve this.
My monitor is connected with an HDMI and images/video are perfect. But I have no sound. If I am playing a video I can see the bars going up and down, but still no sound output.
I have tried using an older version of the AMD software, tried updating the drivers manually, tried a custom install of AMD software and checked the HDMI is the default sound out-put.
I am not a complete noob, but answers in plain English would help. I am not sure what you need to see or what other information would be helpful, but any help is massively appreciated.
