Is it required that all available data has been committed between calls to snd_pcm_ioplug_avail_update() on an IO plugin capture stream? If this is not a requirement then there can still be uncommitted data in the mmap after the current appl_ptr. This data will get overwritten by the transfer call. If it is a requirement then snd_pcm_rate_avail_update() seems to be doing the wrong thing, because it only commits in units of the period size, which means that there could be a partial period left in the mmap. Can someone clarify what the contract is for these calls? Thanks, Rob. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
