I've had a similar problem.  The soundcard works fine for most things but
there are some programs that require DMA and they either stop with a
'DMA error' or (as is the case with "Sound Recorder") give "patchy" results.
Curiously enough just changing the DMA channel that the soundcard used did
not fix the problem.  It turned out that it was the I/O card that was
causing the problem - a little swapping of cards with a friend's machine
showed this.  The dealer that I bought the machine from is quite willing
to change the I/O card for me (I just have to find time to take it to them).
