Title:
  alsa ucm udev rules not working on SDP4430

Status in “alsa-utils” package in Ubuntu:
  Fix Released

Bug description:
  Release:  ubuntu-11.10-preinstalled-desktop-armel+omap4 image
  alsa-utils version: 1.0.24.2-0ubuntu8.1

  I am using the ARM Oneiric image for OMAP4 on Panda and Blaze.
  On Panda the Audioo is correctly configured, not on SDP4430.
  My understanding is that /usr/bin/alsaucm shall set the card in the udev rules.
  Indeed, by running "alsaucm listcards" on Panda or SDP4430 boards, we have following output:
    0: Panda
    1: SDP4430

  I suppose that when alsaucm is used without a card precised, the first
  one is considered.

  In file /lib/udev/rules.d/90-alsa-ucm.rules, replacing the following lines :
  ATTRS{id}=="SDP4430|Panda", RUN+="/usr/bin/alsaucm set _verb HiFi"
  ATTRS{id}=="SDP4430|Panda", RUN+="/usr/bin/alsaucm set _verb Record"

  With:
  ATTRS{id}=="SDP4430", RUN+="/usr/bin/alsaucm -c SDP4430 set _verb HiFi"
  ATTRS{id}=="SDP4430", RUN+="/usr/bin/alsaucm -c SDP4430 set _verb Record"
  ATTRS{id}=="Panda", RUN+="/usr/bin/alsaucm -c Panda set _verb HiFi"
  ATTRS{id}=="Panda", RUN+="/usr/bin/alsaucm -c Panda set _verb Record"

  ... fixes the issue.
  With that rules audio is OK on both Panda and SDP4430.
