Since you've pretty much ruled out software--unless there's some new and bizarre virus infecting your entire household--what's left is hardware. My guess is that something is wrong with one of the input or output jacks--a dirty or broken contact that's shorting it out. This could lead it to believe that some "external device" is connected and totally confuse the CP. You didn't say whether the startup chimes worked. Maybe something fried the speaker; did you try the headphone jack? Two other possibilities: corrupted "Sound Preferences" file or PRAM setting. > ------------------------------ > > S900: also with 9.1 > > I took a CD that played perfectly on a friend's PowerMac (Quadra, with OS > 8), and popped it into the S900, and even a trusty and reliable 7500.

If you are using "iTunes" or "QuickTime Player" this shouldn't be an issue since under OS 9 they both read the data off the CD-DA directly and send it to the sound card, unlike the old CD Player app that controls the CD drive and its digital to analog converter (DAC), sending an audio signal through the cable to the sound card and its ADC/DAC. Check that the files "Foreign File Access" and "Audio CD Access" are present and active in your Extensions folder. Again, preference file or PRAM corruption could possible cause things to be misdirected. HTH, paul -- Paul F. Henegan <[EMAIL PROTECTED]> -- SuperMacs is sponsored by <http://lowendmac.com/> and...
