Please note that S/PDIF is output-only. The S/PDIF connection in the Thunderbolt 3 Dock is driven by a CMedia CM6533N chipset.

This chipset provides the following capabilities over S/PDIF: 

• Two (2)-channel DAC for audio output 
  • mono and stereo source playback supported
  • a limited number of DTS playback environments may allow for 5.1 output, however this is not an officially supported feature.
• Sample Rates: 44.1K/48K/88.2K/96KHz
• Bit Length: 16/24 bits
