Audio from sound card stop working

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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 ?
