I failed to record with the example code 'latency.c' written in the doxygen manual. When it plays back and records at the same time, using snd_pcm_link, should the hardware be implemented as full-duplex of i/o? As previous comments pointed in this lists, some buffer length data are written into a playback handler, and then reading starts. They said, it should be needed to have 4096 bytes written in the write buffer. But in my case, 'writei' continues to return EAGAIN if more than 64byte are to be written. Any comment is welcom. -- UMENO, Junji ElmicWescom, Inc. ------------------------------------------------------------------------- Using Tomcat but need to do more?
