Squeezebox Radio : Switching to Line-in remotely

Hi, I'm looking for a way to switch to "line in" on Squeezebox Radio
remotely (cli, http , ssh , anything will be good :p ).

I know, I read this post which say that it is not possible.

But I also see how to run an applet from another applet ('this one'
(https://forums.slimdevices.com/showthread.php?109870-ANNOUNCE-Line-In-Button-Applet-for-Radio&fbclid=IwAR3VNFaOjOhlBu_DNLX-hmjGwgmVGVwLpNRC-OAk3o7QrXKZeMifuiotut0)
allow to activate line-in thanks to a button shortcut).
I also see 'this applet'
(https://forums.slimdevices.com/showthread.php?77494-Announce-Applet-Plugin-for-remote-administration-of-SqueezePlay)
which allow to run any applet function with CLI.
Also interesting : the line-in applet (natively installed) allow to run
some part of code with CLI. It seems that LineInApplet.lua is called

So I think that it is possible ;) 



So I started to modify this file on my Squeezebox Radio  :
/usr/share/jive/applets/LineIn/LineInApplet.lua
and in "isLineInActive" function of this file I add :

Code:
--------------------
    self:_activateLineIn(initialPlayMode)
--------------------


So now when I run the command on the server CLI:
00:xx:xx:xx:xx setlinein linein

It switch on the line in 😄 ... but it start an infinite loop and
crash the squeezebox 😩 (due to _activateLineIn function which
call again isLineInActive function).
I tried to avoid the loop by checking the state of the checkbox (without
success).

So I've edited _activateLineIn function. To avoid this loop, I've just
commented this line :

Code:
--------------------
    appletManager:callService("goNowPlaying")
--------------------


No crash anymore ... But my Squeezebox is always on line-in...

May be a good developer could have great idea to make it works correctly
!

I share a folder (35621  <-- click here) with these
folders included :

LineIn (native applet on squeezebox - modified) -> the files from my
"/usr/share/jive/applets/LineIn/" Squeezebox folder, I was mainly
working on "LineInApplet.lua"
LineInButton (applet good exemple to trigger line-in) -> Perfect example
to trigger the right lua function (not modified)
LineIn (server native plugin) -> this is the native plugin "line-in"
which allow to trigger "LineInApplet.lua" thanks to the CLI command
"xx:xx:xx:xx:xx setlinein linein" (not modified)


Thank you.
