Subject: Relation between SND_PCM_IOPLUG_HW_PERIODS and SND_PCM_IOPLUG_HW_BUFFER_BYTES ?
Date: Fri, 30 Apr 2010 13:59:55 +0200	[thread overview]

Hi,

what is the relation between SND_PCM_IOPLUG_HW_PERIODS and
SND_PCM_IOPLUG_HW_BUFFER_BYTES ?

While SND_PCM_IOPLUG_HW_BUFFER_BYTES is the setting of the hardware
buffer size, I'm not sure exactly what SND_PCM_IOPLUG_HW_PERIODS is.

I suppose it is the number of periods the hardware buffer can take ?
Hence the SND_PCM_IOPLUG_HW_PERIODS value is actually derived from the
size of the hardware buffer ?

Or is it rather the number of periods the ioplugin can receive at once ?

Please enlighten me,
cheers,
Stefan
