Both HDMI and optical pass digital audio from one device to another. Both are better than analog (the red and white cables). The biggest difference is that HDMI can pass higher-resolution audio, including the formats found on Blu-ray: Dolby TrueHD and DTS HD Master Audio.
Does Optical Cable affect sound quality?
So if you’re getting a Dolby Digital signal, and it’s not cutting out, your optical cable is fine. If you’re transmitting PCM, the audiophile answer is that different optical cables can cause different amounts of jitter. The reality is, the digital-to-analog converter in your gear has vastly more effect on the sound.
Is optical better than RCA?
Coaxial cables are just like optical cables, except the latter transmits digital multi-channel audio as pulses of light versus the former, which delivers an audio signal instead. This is why optical cables offer superior sound quality and HDMI offers superior video and sound quality to RCA.

Is optical digital cable better than HDMI?
In fact, some have claimed that Digital Optical cables relay slightly better sound than an HDMI cable. These types of cables work through using a pulsing wave of light to relay audio signals from a source to a receiving device. Optical cables are popular choices for those with a home theater system as they do provide quality sound.
Does HDMI support sound?
