Hello @jbruno,
I apologize for the delay on this topic.
We were initially unable to use the HFP profile with pulseaudio.
Therefore we did not reproduce the exact problem that you have.
That being said, one of our domain experts is looking into the echo problem and is working to reproduce the problem, so updates are expected soon.
I see that there was another post from one of your colleagues with some additional information here: Integrating Pulseaudio with YOCTO Recipe - #2 by ToradexAI
Is it OK if we continue following this topic there?
Best Regards,
Bruno
