[pjsip] Audio Stuttering in SVN?

So it seems the stutter is not caused by the new jitter buffer then.
If it is caused by loud mic volume, it should be easily solved by
lower the sound device mic volume (not pjsua volume). I assumed you
have tried this as suggested by Atik.

Does that happen for all codecs?
For example: PCMU or GSM which has (much) lower computation than Speex
WB (default pjsua codec for desktop).

nanang
