I get 26 samples regardless of sample rate with the PCI128 and the
kernel driver. That is, all measurable latency seems to be in the
digital filters in the CODEC, and/or the driver + DMA.
(I have a problem with ALSA and input, so I can't get reliable
results with it. Discovered that when running the audio input through
the "reverb" in my softsynth... The same full duplex code.)
