Right now, we are using a arm box with linux kernel 2.6.14 to develop a voip solution. After the rtp connection was connected at first 20 secs, there is no delay. As the timing passing by, the delay will going longer and longer. After 16 houres, the delay will up to 12 secs.
If the sending and the receiving computers don't use the same clock, there will be a small difference in the sample rate. You have to measure this and adjust the data accordingly (by resampling or just adding/dropping some samples).
Because the alsa lib application can't detect any alsa device,
I'd guess that either the device nodes in /dev/snd/ or the configuration files in /use/share/alsa/ are missing.
