[pulseaudio-discuss] Need help to enable echo cancel in pulseaudio

[ABDUL MOIZ]

Hi,
         I have run in gdb and below is the log messages

(gdb) run
Starting program: /usr/bin/pulseaudio
[Thread debugging using libthread_db enabled]
process 1801 is executing new program: /usr/bin/pulseaudio
[Thread debugging using libthread_db enabled]

Program terminated with signal SIGKILL, Killed.
The program no longer exists.

I have run also using strace utility and below is the last lines of log
