Can I still control the volume via the DB RC, if i connect a surround system to my DB5620 via Optical SPDIF? And is normal stereo passed out on the optical output?

The spdif ouput is a digital audio stream. To change the volume of the output needs DSP (digital signal preocessing) which adjusts the digital value representing the level by a gain factor +/-. This can be done by a software processor or an asic chip (application specific integrated circuit).
All the spdif outputs that I have encountered are fixed level -- the output coming off the pin of the asic that strips the audio off the transport stream.
You then process it outside the receiver box.
Some of us with a dBox1 (1997) soldered a wire onto that pin and fed it to a spdif socket screwed into the modem hole. That way, I caught digital audio stream from e.g. BBC rdio straight into DAT or a VXpocket on Mac to make CDs for archive. (Im on radio a bit and I do my friends also when they are on.)
