No, a nebude problem v tom MP3? Nerobi pred tym nez nieco posle cez spdif ako konverziu na raw data ktore posiela?

Takze tu by som videl problem:

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 formats (other than 2ch LPCM) such as Dolby TrueHD and DTS-HD Master Audio, that require greater bandwidth[2] like that available with HDMI or DisplayPort.
