Oh yes my mistake.
but.. :)
i run test...here is log:

I don't see what is wrong...how it can help me in my problem...?
All tests were successfully and i hear all and clear.
next... and again :)
One thing before i starting... word "bursting" in topic is not good...
it's like audio is omitting , drop-outs...
when i run countdown in original is it:
10 9 8 7 6 5 4 3 2 1 0
but i hear:
10 "stutters" 8 7 6 5 4 3 2 1 0
I create own aplication base on pjsua API. Is very similar with simple_pjsua.
this application run on my ARM device with CPU:

// more value give better results but not enough :)
media_cfg.snd_play_latency = 400;

on second side (PC) i ussing pjsua application.
i try describe all cases from wiki:
http://trac.pjsip.org/repos/wiki/sound-problems
Types of Problems
1. No audio is heard on local speaker during the call
- it's ok
-----------------------------------------------------------------------
2. No Audio is heard by remote party
- it's ok
-----------------------------------------------------------------------
3. Audio breakups
- no
-----------------------------------------------------------------------
4. Audio drop-outs or "stutters"
- yes i think this is my problem
1. Check whether the symptom is observable when looping the microphone to
the speaker locally.
2. Check that there is no dangling call in the PBX. A dangling call
is call that is left active in the PBX because previous (pjsua)
application has crashed.
- no this is ok
3. Check for network impairments of incoming RTP packets
- no i have local 100Mb network. here is dq from pjsua
[DISCONNCTD] To: "pc2" <sip:pc2 at 192.168.10.123>;tag=as62decd28

RTT msec : 0.000 0.000 0.000 0.000 0.000
4. Check that CPU Utilization is not Too High
i turn off EC in pjsua --ec-tail 0. In my application i set
media_cfg.ec_tail_len = 0; CPU load is now cca 40-50%
before 80-90%
5. Try to enlarge PJMEDIA_SOUND_BUFFER_COUNT value by setting it in
your pj/config_site.h. The default value is 6, and you can increase
it to, say, 16. But be aware that enlarging this buffer will
increase the audio latency, so you should find a minimum value where
the sound quality doesn't break.
I did but no change (i set to 16)...only log output is different
from lot of logs like:
Master/sound 289 samples reduced, buf_cnt=2267
Master/sound Underflow, buf_cnt=122, will generate 1 frame
i got
13:10:16.269 Master/sound 160 samples reduced, buf_cnt=1244
13:10:16.271 Master/sound Buffer size adjusted from 1404 to 1244

13:10:18.413 Master/sound 128 samples reduced, buf_cnt=2359
6. Check for audio underflows/overflows
i have underflows/overflows...and what can i do for minimum overflows?
-----------------------------------------------------------------------
5. Loud static noise
-no
-----------------------------------------------------------------------
6. Soft/quiet noise
-no
-----------------------------------------------------------------------
7. Audio stutters when streaming tone to X-Lite/SJPhone
- no
-----------------------------------------------------------------------
8. High jitter value observed by remote party
i read
http://trac.pjsip.org/repos/wiki/audio-check-sound-device-jitter
...exist some solution for "bad" jitter?
-----------------------------------------------------------------------
All Checklists
-----------------------------------------------------------------------
1. It's always recommended to check whether the problem exists with the
latest SVN version of the libraries.
-i try but same problem
-----------------------------------------------------------------------
2. Check that the correct device is being used.
- yes is.
-----------------------------------------------------------------------
3. Check that no other application is using the devices. It is common to
not be able to use sound device when the device is being used by other
applications.
- only my application using sound device
-----------------------------------------------------------------------
4. Check that speaker is functioning properly by looping-back microphone to
speaker device.
-----------------------------------------------------------------------
5. You can also check that speaker is functioning properly by playing a WAV
file to speaker.
when run pjsua as :
./pjsua-arm-unknown-linux-gnu --clock-rate=8000 --snd-clock-rate=8000 --no-
vad --ec-tail=0 --playback-dev=3 --play-file cd8.wav
and cc 1 0
...sometimes i hear stutters in sound.
-----------------------------------------------------------------------
6. Check that incoming RTP packets are indeed received by local host
- i think this is OK
-----------------------------------------------------------------------
7. If no RTP packet is received, try this to get around NAT problems
- i don't use NAT
-----------------------------------------------------------------------
8. Check for high network jitter, packet loss, etc.
-----------------------------------------------------------------------
9. Check that the call is connected to the sound device in the conference
bridge.
- yes is.
-----------------------------------------------------------------------
10. Check that CPU utilization is not too high
- 40-50%
-----------------------------------------------------------------------
11. Check that pjsua is transmitting RTP packet to the correct address
- it's ok
-----------------------------------------------------------------------
12. Check that codec is negotiated properly by both parties.
- it's ok
-----------------------------------------------------------------------
13. Checking the echo cancellation effectiveness?
- i turn off EC
-----------------------------------------------------------------------
14. Record the audio with pjsua for to hear it offline
-----------------------------------------------------------------------
15. Check the performance of the sound device
i want try sndtest but i can't find it.
is still in distibution?
..but i found pjmedia-test:

16. Check for audio underflows/overflows
-----------------------------------------------------------------------
...and little example:
i run my aplication on ARM and pjsua application on PC:
You can hear drop-out in record.wav at cca 30s.
original sound and record sound:
http://158.193.202.22/~focus/sounds.tar.gz
that is all :)
can my somebody help? i don't know what is wrong i don't understand what is
inside pjsua core and don't want read source code :)
i just want know what mean and how can i prevent these logs:
233 samples reduced, buf_cnt=877
Master/sound Underflow, buf_cnt=0, will generate 1 frame
JB shrinking 1 frame(s), cur size=32
jb updated(1), prefetch=12, size=3
PS: i try last PortAudio library and same problem...
thanks
