Teams conference call audio gets worse slowly

New Contributor

I've tried to look for the topic everywhere, but I did not succeeded to find any similar problems yet.

 

Problem is that when I start conference call via teams - sound quality is great but then slowly gets worse. I do use Bluetooth headphones it would use this "hands free telephony" service of my earphones.

But then after few seconds - sound levels would increase quite a lot by itself and also background noises (while speaking) would appear. These noises appears usually when sound volumes are turned up to much.

To me it seems like app tries to increase these levels automatically. I've switched off all noise reduction services, also switched off "Automatically adjust mic sensitivity" - does not help.

I would go to Control Panel\Hardware and Sound\Devices and Printers, double click my earphones and to services, I would disable "handsfree telephony" - sound would disappear on the conference call. I would enable it again and sound quality becomes perfect. And again after few seconds - something would increase volume levels and that background noises would appear.

 

I cannot find that thing which does that. Would you help me?

@skirtum I'll guess it's not a Teams certified headset, and to be honest all sorts of random problems occur with non-certified devices.

 

It sounds like you've disabled Teams auto-gain adjustment, but that wouldn't effect what you hear anyway, just your level to other people. It sounds maybe like sidetone, where the headset is playing back some of your own microphone input played through your ears to make it easier to judge your own volume. From your description it would seem to be occurring all within the headsets own firmware.

@Steven Collierthanks!

 

It is not certified I guess. I'm using these earphones: https://koss.com/products/porta-pro-wireless.

 

It was working perfectly with Teams on my previous pc. Got new one and that problem occurred.

 

I do not remember how my old pc identified my earphones, but this one gets me two identical instances of "hands-free" things:

Is it normal? How do you think? Not sure if there is a way to disable one of these?

I've tried to remove it from Bluetooth devices, add it once again and unfortunately I get the same problem.

I still have a hope, that there is some kind of automation, which I could switch off...

I mean I can live with that, but that background noise would tire me quite a lot in longer meetings...

@skirtum Sorry no idea, this is more of a question about these specific headphones than Teams.

Yeah. It looks like Teams is not the fault here at all. I just had a meeting via Zoom and problem was there.
I would blame Windows in this case, as on previous PC I did not had any of such issues. I'll try to play with the settings once more, maybe I'll get somewhere.
