Fixing Elgato 4K X that has no sound

We have been using the Elgato 4K X for over a year and it had been flawless. Yesterday I did my first firmware update to version 24.12.10. Nothing had changed the same software, OBS Studio, same HDMI and USB-C cables we had no sound, but we had video. The HDMI goes from the XBox Series X to the Elgato, then to the TV. The Elgato connects via USB-C to my M2 MacBook Pro.

After doing some research I found the solution. It seems the EDID setting had changed in the Capture Device Utility. I am not sure what the setting was before.

According to the Elgato documentation, Merged should be the default. Mine was set to Display. The screenshot below shows where the setting is changed. It shows Internal which did fix my issue, but I have sinced change it to Merge as that is the default.

My introduction to computers started at my middle school in 1981 when our maths teacher brought in a ZX80. That led the computer club being founded and using a Research Machine 380Z

My first computer was a 48K ZX Spectrum which I loved to programme. Once I left school I worked as a photocopier engineer, then a fax engineer and finally moving on the Apple computers.

For the next 30 years I worked as a system administrator. I now work in the cyber security industry as a Sophos Professional Services consultant
