I did some tracks and found that the PaOssStreamComponent_BufferSize( component ) "in pa_unix_oss.c line 1065" returned 69689344, and that's huge. What really happens here. While I tried app "./pjsua --capture-dev=0 --playback-dev=0" the PaOssStreamComponent_BufferSize( component ) returns 0. Anyone has the same experiences here? Thanks. -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.pjsip.org/pipermail/pjsip_lists.pjsip.org/attachments/20081101/98b63b3e/attachment.html>
