234 interleaved samples at input (#SND_PCM_ACCESS_RW_INTERLEAVED access method),
236 #SND_PCM_ACCESS_RW_NONINTERLEAVED access method) at input. There are these
250 access to memory areas via #snd_pcm_mmap_begin() function.
262 these functions discards the benefits of direct access to memory region.
330 ALSA knows about five access modes. The first three can be used for direct
331 communication. The access mode #SND_PCM_ACCESS_MMAP_INTERLEAVED
334 The access mode #SND_PCM_ACCESS_MMAP_NONINTERLEAVED
338 access mode. The sample organization does not fit the interleaved or
339 non-interleaved access modes in the case. The last two access modes
340 describes the read / write access methods.
341 The #SND_PCM_ACCESS_RW_INTERLEAVED access represents the read /
342 write interleaved access and the #SND_PCM_ACCESS_RW_NONINTERLEAVED
343 represents the non-interleaved access.
