(BTW, I would've never have guessed the -w option; my man file has -2 for conversion to 16 bit.) > $ sox asskickd.wav -w -r 44100 -t alsa hw The words "current event" are no longer repeated at the end of playing. There is a click at the end of playing - hard to know whether it started to repeat something or whether it is truly at the end of the sound file. > $ sox asskickd.wav -w -r 44100 -c 2 -t alsa hw Repeats the "al" bit of the last word "pal" at the end of playing. >> I suspect you are right - the symptoms I have observed (complete >> system crashes) are separate from what Bob observes.

Maybe even a specific chipset bug on his machine? No > idea how different/similar your machines are... I have another PWS600au - a little older than the one I was testing on. It is slightly different in that its scsi controller is a separate board in a PCI slot, rather than on the motherboard. Also has an ESS1888 rather than an ESS1887. Just installed the same OS and kernel on it. Tried playing sound. What a mess. Crashes with mmap on. Installed the patch turning off mmap. Just produces buzzes and fart noises whatever sound file I try to play; both with aplay and sox.
