I use a RME9652 hammerfall with two periods (the hardware is that way).
I watch a file descriptor associated to the output with select(), when it gets ready for writing, I write data to the pcm with snd_pcm_writen(). In the beginning, the state of the pcm is PREPARED. What I would expect then, is that the file descriptor is ready for writing until the two periods has been filled with data, and then select will block (output buffers full, sound card not running). But instead, when the two periods is filled with data, select() still returns and says that the file descriptor is ready for writing, but when calling snd_pcm_writen(), it returns -EPIPE. The pcm state is still PREPARED. What is wrong? Is it me (probably), or is it alsa? /Anders Torger ------------------------------------------------------- In remembrance www.osdn.com/911/ _______________________________________________ Alsa-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-devel
