Hi,

I am trying the webrtc AEC, and pulseaudio gets killed with SIGKILL when using
relatively "higher quality" formats.

The issue happens if I load module-echo-cancel with use_master_format=1 (in my
case that's format=s16le rate=16000 channels=4), but does not happen when using
lower quality formats, e.g.: "format=s16le rate=8000 channels=4"

I can work around the issue and make the master format work by loading
pulseaudio with --realtime=false

JFYI, I am using the standard kernel shipped by Debian, the CPU is a very old
AMD Athlon(tm) 64 X2.

Thanks,
   Antonio
