HDMI 2.1 enhances the overall audio-visual experience but does not directly improve sound quality. Instead, it supports higher bandwidths allowing for more detailed and richer visuals, higher resolutions and frame rates, and features like eARC (Enhanced Audio Return Channel). eARC facilitates better audio signal control and can support more advanced audio formats like DTS:X and Dolby Atmos, indirectly contributing to an improved sound setup. However, sound quality improvements are reliant on the audio equipment and formats used, rather than the HDMI 2.1 specification itself.
