Excellent:
  ~> sox -r 44100 -c 2 -e s -t alsa hw:4,0 -d
works just fine...  except that there's about 0.25 sec latency.
If I don't specify the rate:
  ~> sox -c 2 -e s -t alsa hw:4,0 -d
(or if I specify it correctly as 48000), then there's "only" about
0.14 sec latency.
Is this due to sox ? If so, can I reduce it further ?

Is there a way I can connect hw:4,0 directly to hw:0,0 to see
how much latency there is in alsa and the kernel-modules ?
(E.g. at the midi-level, I can do it with aconnect...)
