I seem to have a crackle now and again on the audio within recordings on my eufycam 2c, when people are speaking for instance you can just hear a sight break/click/blip in the sound sometimes which is a bit annoying… anyone else had issues? 
Also, not sure is related but upon setup the Homebase 2 sound was very crackly and cutting out (seemed to have just been at the start with the speaking bit though, no crackle on alarm tests done since)
