When using a DVI adapter with HDMI cable how is sound processed?

DVI does not support audio, so an adapter or converter is needed. Adapters are passive, meaning they do not process audio. Instead, they split the audio signal from the HDMI cable and send it to an external audio device, such as a speaker or amplifier. Converters, on the other hand, are active devices that convert the digital audio signal from the HDMI cable into an analog audio signal that can be played through a speaker or amplifier.
