Cracking spark sound when turn the key to start

(2006 Hummer H3)
When turning the key sometimes it makes a cracking spark noice. The radio is off but reads Delphi when it usually reads HummerH3, I had spark plugs/ wires changed, do I need to change the ignition coil also? This problem is worse in cold weather!
What seems to make the problem better or worse? Warm weather
How long have you had this problem? A few months

Hello, my gut is that there could be low battery voltage causing the audio unit to reset and the cracking noise. But this is totally a guess and having someone hear the noise who has experience as a technician would almost certainly assist in pointing you in the right direction!
