I have this microphone bug on my ipcam: When i use registred profile on splitcam (obviously) and i speek, on my ipcam (with itegrated mic) my voice is repeated 2 or 3 times as an echo (such as the Pope when he speeks in St. Peter Square).
A little workaround that i found is: to delette my ip cam from splitcam profile and re-add the same ipcam, so it work fine until the next close and restart splitcam software (
It isn't a my pc audio configuration profile it is just a problem of splitcam and its microphone drivers
My pc configuration is: W10, Intel 7700, audio integrated (realtek), IP CAM Tapo C200, split cam version 10.5.12 (the last)
