When I booted up one of my FC2 installs after adding an Hauppauge Win TV Express PCI card, an entry was automatically made in /etc/modprobe.conf as below. alias char-major-81 bttv Using xawdecode I got images ok, and /sbin/lsmod showed that the various modules to do with bttv were loaded. I had no sound and that's what I've been working on for about the last 3 weeks. I have the TV card working ok on FC3, and Kubuntu with sound now, but for some reason FC2 will not load bttv at bootup now. I can load it manually with modprobe, along with all the necessary options, and the card works with sound, and images. Anybody have any ideas? And what is this "char-major-81 bttv" that was created when the card was first detected? During my trying to get the sound working I found a list of these char-major entries, but don't know where I found it now. Anyone know? Very frustrated. Nigel.
