How to avoid "Scalar volume control not supported with this device" ?

Hi,

is there a component, which helps adjusting the volume when I get this error?

Code: [Select]
Scalar volume control not supported with this device
Please use volume up / volume down menu commands or keyboard shortcuts.

I'm playing music via foo_out_upnp and trying to change the volume from a device which has no keyboard (say, my phone via foo_beefweb or foo_httpcontrol).

Ok,
I searched the forum(s) again, but maybe, I just don't know the correct terms to look for.

Anybody has a clue?

(Or maybe a technical explanation, WHY this is not possible, if so ?)

Originally, foobar2000 volume control was performed by setting an exact value - in decibels - by which the audio should be attenuated from the nominal level.
This does not work with UPnP, as various UPnP devices have their own volume scale, chosen by the manufacturer. An alternate way of controlling volume was introduced with foobar2000 v1.2, so the volume value of UPnP device can be manipulated, only allowing it to be increased or decreased by safe small amounts. By the way, you really don't want the classic volume slider shown with UPnP devices, accidentally setting volume to the maximum could have disasterous consequences.
Default User Interface as of foobar2000 v1.2 was updated to show the (-) (+) buttons instead of the slider when foo_out_upnp is selected, other components should have done the same but it seems not everyone got the memo. Please ask authors of those components to verify compatibility with foo_out_upnp volume control.
