[alsa-devel] Question on buffer size setting

[Allyn, Mark A]

Hello:
 
I am attempting to do some debugging of a new audio device, and I need
to change the
number of buffer descriptor list entries from the default of 16 to
something much
smaller, like 3.

I am a bit confused while looking at the code. There seems to be a value
labeled
SNDRV_PCM_HW_PARAM_BUFFER_SIZE, but I can't figure how it is set. Is
this a parameter that
is passed as part of the configure prior to doing a make for the driver?
Is this a parameter
passed to modprobe when loading the driver? 

Thanks for your help.

Mark
