Viofo cameras have never had a great sound. Most likely, Viofo considered that a high level of sound on the recording was more annoying than useful. Personally I agree and prefer a low sound level. In general, I keep the sound mute for some reasons quite important at least for me, probably the same for many other users.
However, I think that adding a sound level setting to 2-3 levels in the menu would be a solution that would reconcile everyone.
