I got my replacement Kodak Zi6 today, and this one has an even more severe offset in the audio (about 12db) than the last one. That’s pretty disappointing. On the plus side, it’s running a newer firmware build which allows you to disable the annoying chimes.
For now though, I guess the message is to avoid the Zi6. I know there are good ones out there, without this issue, but obviously it’s not that uncommon an issue.
