Hi list, after making test I have realised that there is a bug in the alsa_dev files. I am using pjproject-1.4. If I play a wav file using an ALSA device I hear noise, not audio. But if I use another device, I can hear very good the audio. I have tested without the conference bridge, so I have observed the error must be in alsa_dev.c Does anybody knows where can be the error? Thank you very very much! Alicia -------------- next part -------------- An HTML attachment was scrubbed...
