I have been preoccupied with other things for the last couple of weeks so haven't had a chance to try it out. > There's a patch attached that disables mmap on MIATA.

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 performing. 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. Michael.
