Yes, I've read that before actually.
I noticed that SPDIF outputs are shown without volume bars in ALSA mixer. Does it mean that software volume control (like in KDE) will have no effect on such setup, and using the hardware volume dial on the amplifier is the expected method? I.e. SPDIF is supposed to be just a pure signal, and the rest handled by external hardware? Or PulseAudio volume control will still have an effect on it?

Setting player/SPDIF less than 100% means you start losing detail depending on the material. There is a limited number of bits after all (unless you pad with larger bit depth). I don't know if pulse forces some additional signal processing, but this should be the "purest" setup.

That's what Audacity displays for audio by default:
View cookie preferences.
Accept & Show Accept All & Don't show this again Direct Link
Realtime audio visualizer can display it by storing some amount of history of what was played before I suppose.
