I beg to differ. Especially because some AD/DA's introduce quite a bit
of additional latency. When i used my cs46xx based card i had to go down
to 32 frames to get an acceptable latency for playing my guitar through
jack-rack. I once measured the roundtrip latency of this card and found
out my AD/DA's added another 4-5ms of latency to the 1.333ms latency
which were caused by the periodsize of 32 frames. And it seems 6ms total
latency was fine for me :)
