Adapters Will be Needed in Most Cases

This KVM switch supports HDMI digital output only. Make sure you select HDMI Audio Output or Monitor A audio (monitor on HDMI Out A) as default in your sound settings. Do not select your audio device as default sound device, otherwise the audio would not work properly. Some older monitors which do not support HDMI audio will not work with the audio function. The workaround is to add an USB to Audio adapter (Ref. ASIN B00IRVQ0F8) to one of the USB 3.0 HUB ports on the front panel.
