OK in my research here is what I found..... I seem to get the idea from what I read that ztdummy is not needed for 1.2 (and above) versions for anything but meetme. I never used ztdummy in my old system and it worked just fine. I really see no difference here with it running or not. Please confirm - is this timing required for just simple wav/gsm playback - like voicmail, etc. ?
I played around with kernel options.... echo 0 > /sys/devices/system/cpu/cpu1/online echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor Which essentially makes it a 1 CPU system at max performance. NO CHANGE. Then put it back... echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor echo 1 > /sys/devices/system/cpu/cpu1/online Tried this.... echo 1 > /sys/module/processor/parameters/max_cstate Default was 8. NO CHANGE. Let me reconfirm what I am hearing. The audio choppiness is subtle but definitely there. It seems to happen at the exact SAME place everytime I play it, which is suspicious! Could this be sometihng completely different then what we are suspecting????? It seems to get out of sync. sometimes it seems it is playing future audio on top of current by only Ms's or maybe it is putting a hole there. Hard to tell. OH I also tried compiling with the O2 optimization rather then the O8 in the default Asterisk Makefile. Again NO CHANGE. Any more ideas would be helpful.
