I am using CentOS 7 x86-64 which is pulseaudio 6 based. Everything works fine with pulse audio totem plays fine, aplay works fine.... except Asterisk. I am running in system wide mode. I hear audio with asterisk but is crackly or has static in the audio. I have tried the tsched=0 that made no difference. What can I do so asterisk is as clean sound as totem and other programs?
