hmm, this seems _really_ odd to me. The mechanisms used to read from an
ALSA and OSS are almost identical performance-wise! :o
My guess would be that ecasound is triggering some bug in the ALSA
driver for h2200. You could try recording with "-z:noxruns", and see if
the output file is ok (maybe the xruns are falsely detected). You've
probably already tried with "-z:nointbuf"...?
If the same happened with both OSS and ALSA (but worked on arecord), this
would be easier to explain (ecasound uses float math, arecord doesn't ->
this can make a huge difference on devices without hw-based float math ...
but, but, h2200 should have enough horse power to do some simple
operations even in float).
