Win10 forced a recent upgrade on an HP computer that had been migrated from Win8 to Win10 years ago. The upgrade resulted in the loss of audio options, and was stuck with HDMI audio to a monitor that had no speakers. This gizmo restored sound to a computer that had been muted!
Also, had a widescreen TV that lightning had taken out the HDMI ports and the internet port. The VGA and audio ports were still working. This allows the HD TV can now be used with ROKU and other devices that have HDMI outputs with HDMI audio.
Kept multiple electronic devices from the landfill!
