Just tried it and can confirm it's working without a buffer. I took a TOTX147 (cheap on ebay) and connected GND, +3,3V and SPDIF signal + 100nF between GND and 3,3V.
With 4.4.77-rockchip-ayufan-118 spdif audio out is working on hw:2,0 with 16bit and 44,1kHz, 48kHz and 96kHz. No luck with 24bit or dts/ac3 so far.
