My setup is stock. Shielded 18G 3 strand in the fuse for nav, strobe, and sync. Unshielded to the tips connected at the wing root. Strobe ground and light ground connect together and run to the wing root where it attaches to fuse. Shield in fuse length grounded at wing root fuse.
Heated pitot with no controller has twisted 14g in the wing with a ground at the wing root.
No noise in my GMA245 audio from lights or strobe. All AeroLED. Gmu22 in the left wing doesn’t blip at all. Probably will help to look at your audio jacks and make sure they aren’t grounded in any way and that your shields for audio are exactly per plans.
