I'm having trouble getting the echo-cancel module working. I'm running pulseaudio 15.0 on an i.MX8QM arm embedded system, and trying to do echo-cancel between the speakers and the mic to act as bluetooth speakerphone. For testing I am playing music through the echo-canceled speaker sink and running parecord on the echo-canceled mic source. I can do either of those independently and it works. However, when I start parecord while playing through speakers, pulseaudio goes to 100% CPU and journalctl shows the error "Resume failed, couldn't restore original sample settings." streaming over and over. Tried with aec_method=null for test purposes and got the same result.
