| What is in your /etc/modprobe.conf file?
|
| What is the output of "lsmod"?

| What messages appear in /var/log/messages when you plug in your

Mymodprobe.conf shows:

alias snd-card-0 snd-intel8x0
install snd-intel8x0 /sbin/modprobe --ignore-install snd-intel8x0
&&/usr/sbin/alsactl restore >/dev/null 2>&1 || :
remove snd-intel8x0 { /usr/sbin/alsactl store >/dev/null 2>&1 || : ;};
/sbin/modprobe -r --ignore remove snd-intel8x0

~ # Turn off IPv6
alias net-pf-10 off
alias ipv6 off
alias usb-controller1 uhci-hcd

lsmod returns:
