LinuxQuestions.org - Device changed names after Kernel Update

hello!
After my latest kernel upgrade some devices changed their names like eth0 changed to eth1!

this stuff is causing some conflicts in my computer.
I'm pretty sure /dev/dsp changed it's name 2, but I don't know to which one of the other dsps or maybe other name, cause I don't have sound at the moment :(

here's ls -ltr in /dev/dsp*

Code:

zuki@WhiteCastle:/dev$ ls -ltr dsp*

crw-rw--w- 1 root audio 14, 51 2003-08-29 10:47 dsp3

crw-rw--w- 1 root audio 14, 35 2003-08-29 10:47 dsp2

crw-rw--w- 1 root audio 14, 19 2003-08-29 10:47 dsp1

crw-rw--w- 1 root audio 14,  3 2003-08-29 10:47 dsp0

lrwxrwxrwx 1 root root      4 2006-10-20 16:59 dsp -> dsp0

what to change the ln -s of /dev/dsp to ?\
and most important, why?
Thanks!
