[alsa-devel] Question on buffer size setting

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
