Hi: Yeah, /dev/audio is mainly found on Sun machines. The presence of it in Linux is to provide emulation for the Sun /dev/audio device for programs that need it ... like speak freely. Note that you can make Speak Freely use /dev/dsp by uncommenting the -dneeded_liniar define in the makefile. This also works for getting around buggy implementations of /dev/audio (notably in some OSS drivers). Geoff.
