What is hdmi to hdmi + audio?

HDMI to HDMI + audio converter is a device used to convert the HDMI signal and output the audio in a separate jack. The converter takes the input signal from an HDMI source such as a game console or a DVD player and separates the audio signal from the video signal. This is useful when using an older audio system that only has RCA or stereo inputs or when the TV or display doesn't have a built-in speaker system. The converter can convert HDMI signals up to 1080p resolution and supports a variety of audio formats, including LPCM, Dolby Digital, and DTS. It can also be used to extend the length of an HDMI cable by adding a separate audio cable. The converter typically comes with a power adapter and a user manual, and is easy to use and install.
