The Optical Digital Audio Output on the LG C8PUA 4K HDR Smart OLED TV w/ AI ThinQ® - 55'' Class (54.6'' Diag), Model # OLED55C8PUA carries a digital audio stream to an AV receiver that can decode two channels of uncompressed lossless PCM audio or compressed 5.1/7.1 surround sound such as Dolby Digital or DTS Surround System. Unlike HDMI, TOSLINK (Also known generically as an "optical audio cable" or just "optical cable") does not have the bandwidth to carry the lossless versions of Dolby TrueHD, DTS-HD Master Audio, or more than two channels of PCM audio...^IFV
