Even without it, your processor would be working hard already with sample rate conversion between 44.1Khz and the default native 16Khz used throughout pjmedia. > I have a PJSUA version 1.3 running on another OpenSuse machine and that one > works fine: > > the only difference that I noticed is that when I finish the call, the old > and working version prints out this: > > [quote] > ?22:38:08.206? pjsua_media.c?

I don't recall we made changes to pjmedia-audiodev in 1.4. Cheers Benny > Thanks in advance, > Arthur > ________________________________ > Internet Explorer 8 - accelerate your Hotmail.
