In theory, the Realtek Digital Output is already very good. Because the signal is digital, it isn’t susceptible to electrical noise from your PC’s power supply (no buzzing, hissing, or static). You are sending a pure signal to your receiver or DAC.
Standard optical digital connections (S/PDIF) lack the bandwidth to carry uncompressed multi-channel audio. They can only carry stereo (2.0) uncompressed audio, or compressed 5.1 audio (like Dolby Digital or DTS). Because PC games generate audio in real-time uncompressed formats, using a digital optical cable will limit your gaming audio to standard stereo unless you use specialized compression software like Dolby Digital Live. Note: Ensure you have an Optical (Toslink) cable
A technical limitation to be aware of is that the S/PDIF connection does not have enough bandwidth for uncompressed 5.1 or 7.1 surround sound. Therefore, for multi-channel audio, such as movies, the audio is compressed into a format like Dolby Digital or DTS . However, this encoded signal is then sent digitally, and your external receiver will decode it, still resulting in excellent, high-quality surround sound. For the highest quality, uncompressed formats, a direct HDMI connection is the standard.
