 i try use ATTR{dev}="14:20" but it change after reboot too =(

can i use number of pci slot ? or even more ?

-------- stop --------

but i have not answer =(

i try use externel program and it work now

i cr≈ate file /root/device_namer

#!/bin/bash

PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

if [ `echo $1 | grep "0000:02:03.0"| wc -l` != 0 ]; then
  echo radio1;
  exit 0;
fi

if [ `echo $1 | grep "0000:02:04.0"| wc -l` != 0 ]; then
  echo radio2;
  exit 0;
fi

i bad bash programmist =) then i add net line to /etc/udev/rules.d/10-local.rules

KERNEL="audio*", PROGRAM="/root/device_namer %p", SYMLINK+="%c"

how it work : when system boot udev run some like 
'/root/device_namer /devices/pci0000:00/0000:00:1e.0/0000:02:04.0/sound/card1/.tmp-14-20'
and create simlink what i need
