S/PDIF is based on the AES3 interconnect standard.[3] S/PDIF can carry two channels of uncompressed PCM audio or compressed 5.1/7.1 surround sound (such as DTS audio codec); it cannot support lossless surround formats that require greater bandwidth.[4]
=====================
spdif本身就只能带出双声道的PCM,要么你需要像下面这位仁兄一样,多挂载个ffdshow滤镜,进directshow播放链里,做一道转换成AC3的步骤;或者直接用古董的ffdshow接管LAV的解码工作
