Unable to find ast_debug output

I have a modified version of chan_alsa.c, with some ast_debug messages I’m expecting to see. I am not seeing the messages. I assume I’m missing something silly to enable them, does anyone have suggestions?

I have modified /etc/asterisk/logger.conf to add ‘debug’ messages to the console, but do not see any new output.

When I run

core set debug channel all

I get messages about null frames, but not the messages I’m expecting, and it’s no different after changing logger.conf

did you run “module reload logger” afther?

I think what I was missing was core set debug 9. Thank you for the assistance!
