Hi! Previously my SPDIF headphones (Sennheiser rs185) were unusable when output was set to PCM. Now it seems to work both with PCM and SPDIF passthrough. Can someone tell me which setting is better and what the differences are for music (i.e no Dolby or AC3 audio tracks)? Would it also be possible to have a Simultaneous SPDIF/Analog audio setting?
