I am running Debian Potato on a machine which is totally SCSI ( I feel that way myself sometimes) and includes a PlexWriter CD-Writer and a SoundBlaster Live 1024.
I hadn't used my machine this morning and I happened to enter the room to hear clicks coming from both speakers. I tried lsmod and no sound modules were loaded. I also discovered that every movement of the mouse produced rapid clicks from the speakers. The mouse, by the way, is on IRQ 5 and the sound card on an IRQ above 10. Using the keyboard also produced clicks as did ejecting the CD tray (no CD). I decided to close down and reboot the machine. The clicks continued right through closedown and didn't stop until the machine actually started to reboot. Any ideas? Barry Samuels
