Hi, I'm experiencing a curious problem. My software worked fine during multiple days, but after a random time (or event) the sound from the sound card just stops working and the only log I get is : Master/sound Underflow, buf_cnt=276, will generate 1 frame I can always hear the sound from the system because the media player continue to work. I have checked on dmesg, there are no problem with my sound device (no deco-reco). My configuration : - pjsip 2.3 - linux 3.14.2 - conversation codec is G729 Any idea where the error comes from ? What can I do for debug this kind of problem ?
