I try to play a wav file by using "playfile", it works good. So the sound device is ok I think, any way I will try other steps in <a href="http://www.pjsip.org/trac/wiki/sound-problems">http://www.pjsip.org/trac/wiki/sound-problems

Hi<br><br>I cross compiled pjsua for arm versatile platform with the arm AC97 sound device. But the voice quality was quite bad, during the communication with a pc using X-lite, there is only some noise came out from the speaker. Is it because the cpu power not good enough to decode ? Is there any parameter in the source code can modify for a better voice quality?? Does any one try to run pjsua on the arm platform??
<br>any advice will be great help, thanks!!<br>
