Oh dear. I didn't mean to chastise you for your earlier posting. Especially 
since someone else did offer a suggestion about your problem. All I meant 
was what I actually said ... that your question was outside the range we 
typically deal with here. Please understand that I am no one special, just 
another member of the list. I wasn't trying to give people orders, just 
convey a sense of the list as it has operated historically.

As to your implied question ... when I experience similar problems, I 
usually find that they are pci bus problems, not Linux problems as such. 
(I've had both TV-tuner cards and NICs interfere with video cards, for 
example.) Observe during the early (pre-LILO or -GRUB or whatever you use) 
stages of the boot process to see if your BIOS still sees both the sound 
and NIC devices. If it doesn't, fiddle around ... try changing the slots of 
one of the other device (or just the NIC, if your mobo has on-board sound).

On the Linux end, see if the sound hardware still shows up in the 
"lspci"  listing. Check /proc/interrupts and /proc/ioports for a conflict 
(yes, I know Linux is supposed to share interrupts, but the reality is that 
it works imperfectly at best).

That's about all I can suggest without some details -- what sound card 
(what module), what NIC, and what "stopped working" means (what are you no 
longer able to do that you used to be able to do?).
