Sergio, sorry, but you missed the [HEADS UP], and did it all wrong.



or even better, http://people.freebsd.org/snd_RELENG_6*.diff.gz, or if
you comfortable with binary module,

It is not because of the chip cannot do DMA larger than 4k. It is
because your hardware combination. Smaller DMA means higher interrupt
rate, and your chip need to compete with other peripherals to combat
with that. All this can be solved by just using
"hint.pcm.0.buffersize=4096" without any single driver source tweak.
Note that you probably don't even need this tunable hint if you using
the above "lowlatency" (which itself need another HEADS UP)
