You are correct, play works correctly but catting does not. It seems, however, that many OSS drivers support cat a wav file directly to /dev/dsp, and do the detection of the format parameters internally. I guess this is not required by the OSS specification? -- Ryan Underwood, <nemesis at icequake.net>, icq=10317253 ------------------------------------------------------- This SF.Net email sponsored by: Parasoft Error proof Web apps, automate testing & more.
