After I upgrade my system into cygwin-1.3.2 (my system is Win98se) >cat sample.wav > /dev/dsp will fail. The error message is bash: xmalloc: cannot allocate 7299 bytes (0 bytes allocated) but > cp sample.wav /dev/dsp will works. There is not problem in snapshot-20010519, before change the s_audio into pointer in fhandler_dsp.cc Regards, Topas
