Room kit, Room kit pro audio out some ultrasound shows while proximity disabled

Hi there,

I did recently upgrade codecs room kit and room kit plus to 9.14.6 Endpoint FW - I know now there is now available 9.14.7

Proximity is Disabled at least its status is like that.

What i have found is that when You use analog audio output in room kit and external amplifier You will hear some audio similar to proximity ultrasound. You can do it even with amp. external PC speakers.

There is no sound like that when You use internal room kit speaker.

Does not matter if I use internal mic or external.

This audio is about 20kHz range.

The same problem I have found on roomkit pro with disabled proximity.

In this case I have disconnected the mics and audio inputs, and the sound is still there at the audio output when You try to amplify it.

This is a real problem in larger rooms, and external recording.

 

Could not relate it to release notes or other known issues.

Does anyone have the same problem or can confirm the same problem?
