06 Escalade Radio volume issues

What radio do you have?
Cd/cass or nav

I had a similar issue and it was the radio causing the problem

It's more likely software based vs hardware as the audio pilot mic only compensates for when the engine is running

Now the radio has a vss(vehicle speed sensor) feed in the smaller of the two harnesses that plug into the radio

I kept my old radio when I upgraded of the op wants to try it and see if it helps or not

Also keep in mind the chimes volume is seprate from the radio and onstar volume
Try it with the onstar system running and see what happens(that will help me figure out where the problem truly is)
Fyi the onstar will keep the radio and amp going even with the key removed and the door open(tried it myself) and it works no matter if the system is active or not(mines not active)
