[linux-audio-dev] Newbie has sound card problem

I am a Linux newbie who has recently installed RedHat9 on a Dell Optiplex GXa, 233 MHz, 128MB. Booting from the Dell diagnostics diskette and running tests confirms the Crystal CS4236B integrated sound card is working properly. At the RH9 installation the card was correctly detected by isapnp. I hear some alert beeps through the speakers. dsp, audio and mixer are present in /dev/ with access flags crw------ BUT...... cat <soundfile> > /dev/dsp (or > dev/audio) returns the message "bash: /dev/dsp:No such device" and no sound in spkrs. ALSO the Gnome sound recorder wont record AND the Gnome Volume Control returns the message "Unable to open audio device /dev/mixer" AND the Gnome System Settings/Soundcard detection reports "No sound card detected" I've read the Linux Sound HOWTO but it doesnt help. (perhaps I dont understand it). Where to from here? - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Jo Evans, Network Manager, Computer Support ph ext.3601 University of Auckland ph 64 - 9 - 422 6111 Leigh Marine Laboratory fax 64 - 9 - 422 6113 P.O.
