I got alot of work into this, please post in a thread i will create
specificlly on VISTA AUDIO in RR


A few things....
if you didnt use installer, run "runme1st.cmd" inside "VistaMixerControl"

and if u had the OLD version, feel free to delete the old .dll/.tlb, i think named, MJSVista... 

inside the "VistaMixerControl" directory, is a file called Vista Mixer Control.exe
use this program to IDENTIFY lines that are available for control

example from my system, and it will vary from system to system
the names of the line are INSIDE the BRACKETS [...]


Line 1 - [Front Green In]  	-> Mute=False | Volume=0
Line 2 - [Rear Blue In]  		-> Mute=True  | Volume=15
Line 3 - [Front Pink In]  	-> Mute=False | Volume=0
Line 4 - [Rear Pink In]  		-> Mute=False | Volume=0
Line 5 - [Rear Grey In]  		-> Mute=False | Volume=0
Line 6 - [Rear Orange In]  	-> Mute=False | Volume=0
Line 7 - [Rear Black In]  	-> Mute=False | Volume=0
Line 8 - [Rear Green In]  	-> Mute=False | Volume=0
Line 9 - [CD Audio]  				-> Mute=False | Volume=0


now i have my XM Radio connected to "Rear Blue In", so if i needed to mute / unmute that line (which u technically dont have to)
in rr.ini, xmline=2

now lets say you have a mixer skin... and want a button to increase and decrease the level, and a slider too

/, buttons
B25,285,307,50,40,"VOL+;Rear Blue In",""
B35,285,495,50,40,"VOL-;Rear Blue In",""

/, sliders
S15,300,348,20,146,300,324,20,146,V,01,"pointer.png",20,"vol;Rear Blue In","Line"


NOTE that everything must USE the VISTA LINE NAME (from the above list)
THIS WILL NOT WORK:

S16,360,348,20,146,360,324,20,146,V,01,"pointer.png",20,"CD","CD"

it MUST BE

S16,360,348,20,146,360,324,20,146,V,01,"pointer.png",20,"vol;CD Audio","CD"

NOTE the vol;   meaning CUSTOM volume slider code

**************************************************************************
