NextCloud Talk - always audio echo (smartphone/PC/etc.)

Hello all,

I am using Nextcloud 21 and I have enabled Talk functionality.

I have setup already TURN/STUN on my instance and the TURN test is successfull.

Video and audio are working properly between devices…well, video yes, but audio has always echo.

Basically I cannot use Nextcloud Talk without earbuds, so it is basically useless with other people that does not want to use always earbuds for this app.

Is there anyway to reduce/eliminate echo in Nextcloud Talk? The problem is not there when using Whatsapp.

Many thanks
