I recently bought Asus Strix Soar (ordinary version). I have few few questions and to report strange behavior with Sonic Studio or drivers.
1. Is Soar capable of outputing 5.1 or 7.1 thru SPDIF? Even thou I didn't connected anything to SPDIF, on Sonic Studio SPDIF stereo can be only selected. Question for future AVR 5.1 or 7.1 system. Will aditional options (5.1/7.1) appear when connecting AVR or similar to SPDIF, on SPDIF playback configuration menu?

S/PDIF can only output two channels of uncompressed PCM audio. This is a limitation of the S/PDIF interface, and not specific to Asus STRIX SOAR or any other particular sound card. S/PDIF can transmit multichannel audio but it has to be compressed (Dolby Digital, DTS, etc.). S/PDIF can't even transmit higher bandwidth codecs like Dolby TrueHD (which also happens to be lossless). The only way to get multichannel audio out of S/PDIF from a sound card is if the sound card itself does the Dolby Digital/DTS encoding on-the-fly. This would be computationally intensive, require licensing, and basically be not worth it.
If you want to stay in the digital realm with multichannel audio, hook up an HDMI cable. The point of high-end sound cards like STRIX is to have a quality DAC to drive analog equipment (speakers and headphones).
