I'm getting a small amount of noise in my headset from my GRT Sport EX. I expect it's related to the audio warnings, which I have set pretty loud. Has anyone else seen this, and found a solution? The noise is not that loud, but quite noticeable when it starts during at a certain point in the boot sequence of the EFIS, and, well, I don't want it if I can get rid of it. It's wired directly into my Trig radio audio input port - no intercom. Thanks!
