I changed pi0 to P3, recompiled the installation project, and found that NS was running normally. At present, the gcc compiler used by webrtc ﹣ audio ﹣ processing outputs the so file of armv7 by default. Where can I change it to output armv6 so file that supports pi0

For pi zero, you can try compiling the package from source
