I am compiling 2.11.0 on linux 4.4.0 everything compiles fine... in the old days there was a dahdi_dummy module that got loaded (no cards) is that still the case ?? dahdi_dummy.c is not even compiled. I have CONFIG_HIGH_RES_TIMERS enabled in the kernel. I am getting a warble sound on the sound card using pulse audio, on CentOS 7.2 (Yes with a later kernel :) ), trying to find out why the warble. aplay sounds fine totem plays video and sound just fine asterisk audio - not so good I have tried the tsched=0 and made no difference. Also install libpri 1.4.15 and asterisk 11.21.0 pulseaudio is working great for everything put asterisks. Any ideas?
