Hi @smithy

We haven't been hands-on with this particular model but I would check the below forum post to make sure you have audio settings set correctly.

How-to: - How To Set Up Live View & Playback Audio on Hikvision Cameras

There is a small selection of Hikvision cameras that support some sort of audio - audio I/O, built-in mic, 2-way audio - but on multiple occasions, customers have come back to us saying they are getting no audio on live view or playback. So to avoid this problem in the future we are creating...

Hikvision cameras probably don't do this but when I used a Reolink wireless camera for 2-way "live" audio, it was a nightmare with wifi lag combining with never-ending echoes and screeching feedback. If I forgot to turn my PC audio level down, even a camera with no background noise would play back to me every cough, chair creak and phone ring in my office - descending quickly into a screech.

good point @macman

we have experienced feedback loops with Hikivison cameras when listening to audio through the app and standing close the camera, if you only have camera on test on your office desk or similar it could be a feedback loop from PC speakers, radio, etc... that are in close proximity to the camera, maybe if none of the above fix the problem you could try moving the camera around and see if you notice any change in the sound.
