Alas, this may depend on if a given device/stage applies overall gain when the 'gain' is set to 'max'. My experience of consumer / computer kit is that often they do things without telling you. But you'd need to test or delve into the specs of each device. My problem is that know zilch about the specific items you use. So I can't give a sensible solution I'm afraid. I solve this by always playing as 'directly' as I can using ALSA on Linux and if necessary writing my own code to do so. But I realise this is too 'hair shirt' for most people. If you system has any kind of 'mixer' which lets more than one sound source play in parallel at the same time, expect it to fiddle with the data in ways you might not wish! > I mentioned signal to noise ratio because in my distant memory there is > an underlying principle here, just lost in the mists of time.

With analog signals, each stage will add some noise and distortion, albeit hopefully too small to worry about. But with digital LPCM transfers they should just 'pass the parcel' and deliver at the end of the chain what got put in at the start. How you set this up (and if it is even possible) depends on the details of each device along the chain. As has been said, glitches may well be interference or loss of signal due to other transmissions filling the band slots.
