The Touch firms is setup as a single player with a single volume
control.  LMS slimproto just has volume control for L & R for a player.

AFAIK - there is just one DAC in Touch. 
Touch firmware does volume control on decoded digital stream fed into
the DAC (i.e. firmware does gain, fade, in fade out, cross fade as well
as normal volume control) .  
The digital input stream is sent to DAC and also sent to digital out,
the analog out from DAC is sent to analog circuits (socket  + Phono)

Not possible in the current server? (I'd agree) or not possible ever
because of some fundamental limitation? (that's what I'm asking)

I don’t think this is possible.
I’d look for a line level headphone amp so that you can have both
digital and analogue at 100% and control the headphone volume via the
headphone amp

Sorry... I guess I didn't read it right.  I always use the digital out
so have never looked for the setting.

yes, as I said I would like the ability to turn down the analog volume
while keeping the digital at 100%. Is this possible and or has it been
discussed before?

You wouldn't want volume controlling the digital out... at least it
should ALWAYS be at full volume.  As you change the volume digitally
it's actually truncating bits, so if you're playing 24bit files, as you
turn down the quality gets worse and worse.  Keep it at FULL VOLUME and
ONLY turn the volume down on your D/A converter AFTER it converts back
to analogue.

[SlimDevices: SqueezeCenter] Separate volume for analog and digital outputs

2022-12-09 Thread antagron


Is it possible to set the volume for analog and digital outputs
independently? I believe the current answer is "No" (I'm using a Touch).
Has this feature ever been requested? Is it technically possible? The
use case is I have am using multiple outputs simultaneously and I'd like
digital outputs to be 100% while being able to control the analog output
using the UI (headphones).
