Takashi replied with a suggestion to disable MMAP in the ice1724 driver.
I have been preoccupied with other things for the last couple of weeks
so haven't had a chance to try it out.

I have applied the patch to the PWS600au. Sound now works. I can play
8bit and 16bit sound files through the es1887 and the C-Media CM8738.
They are both working fine. I managed to get a 32bit sound file to play
through the M-Audio Revolution too. (Though another 32bit sound file
just produces silence through the M-Audio Rev. Haven't been able to
establish why - the file looks fine to me.) Repeated playing of files
doesn't cause any problems.
I can't get sox's play to work (reports no mmap support, which is, of
course, quite true). I don't know how to tell sox to use the equivalent
of alsa's hw device. So I can't do the test on short files that Bob was
At this stage I've run out of time to test the M-Audio Rev in the XP1000
and see if the MMAP disable patch help there.
