Hi Peter, Was thinking that the problem was in audio device. However, the pjsystest result says that the audio device tested (UCB1400?) looks okay, i.e: avg interval == ptime == 20ms, also 'acceptable' burst level. And also you mentioned that "All tests were successfully and i hear all and clear.", FYI, "WAV File Playback Test" is the same thing as 'cc 1 0' you've done before :) So, perhaps optimization [1] is needed, e.g: on some Symbian devices, log level should be 3 or lower, otherwise there will be audio impairment. Btw, you were running pjsua with '--playback-dev=1' option without '--capture-dev' option, did the pjsua use the same devices as tested using pjsystest? Please make sure that pjsua using the same audio devices as pjsystest. --- [1] http://trac.pjsip.org/repos/wiki/FAQ#cpu --- BR, nanang On Mon, Dec 14, 2009 at 9:11 PM, Peter Lukac <p.lukac at emtest.sk> wrote: > Oh yes my mistake. > but.. :) > > i run test...here is log: > > PJSYSTEST Report > Time: 2009/12/11 11:49:40 > Tests invoked: 13 > ----------------------------------------------- > > TEST 0: Audio Device List Success > Found 5 devices > ?0: PA [UCB1400: ?(hw:0,0)] (2/2) > ?1: PA [vystup] (0/2) > ?2: PA [dsp0] (0/128) > ?3: PA [default] (0/128) > ?4: PA [/dev/dsp] (16/16) > > > TEST 1: Audio Settings Success > Version: 1.5 > Test clock rate: 8000 > Device clock rate: 8000 > Aud frame ptime: 20 > Channel count: 1 > Audio switching: Conf bridge > Snd buff count: 8 > Rec dev : -1 (UCB1400: ?(hw:0,0)) [PA] > Rec ?buf : 100 msec > Play dev: -2 (UCB1400: ?(hw:0,0)) [PA] > Play buf: 140 msec > > > TEST 2: Audio Tone Playback Test Success > > TEST 3: WAV File Playback Test Success > > TEST 4: Audio Recording Success > > TEST 5: Audio Device Test Success > Here are the audio statistics: > Rec : interval (min/max/avg/dev)= > ? ? ? ? 0/71/20/6 (ms) > ? ? ?max burst=4 > Play: interval (min/max/avg/dev)= > ? ? ? ? 0/71/20/6 (ms) > ? ? ?burst=4 > > The sound device seems to be okay! > > TEST 6: Audio Latency Test Success > The sound device latency: > ?Min=157, Max=264, Avg=178 > > > TEST 7: Audio Device Test Success > Here are the audio statistics: > Rec : interval (min/max/avg/dev)= > ? ? ? ? 0/61/20/5 (ms) > ? ? ?max burst=4 > Play: interval (min/max/avg/dev)= > ? ? ? ? 0/61/20/5 (ms) > ? ? ?burst=4 > > The sound device seems to be okay! > > TEST 8: Audio Tone Playback Test Success > > TEST 9: Audio Tone Playback Test Success > > TEST 10: WAV File Playback Test Success > > TEST 11: WAV File Playback Test Success > > TEST 12: Audio Latency Test Success > The sound device latency: > ?Min=10, Max=155, Avg=48 > > 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.
