[Bug 506622] Re: linux-backports-modules-alsa-2.6.31-18-generic in proposed no longer works on a macbook pro 5, 3

[DavidP]

** Description changed:

  dperson at argos$ alsamixer
  No mixer elems found
  
  With linux-backports-modules-alsa-2.6.31-17-generic, sound just worked.
  Now it has an unknown symbol error when trying to load the backported
  "snd.ko"
  
  TROUBLESHOOTING:
  
  dperson at argos$ lsmod | grep '^(snd|sound)' | awk '{print "rmmod "$1}' |
  sudo bash
  
  dperson at argos$ sudo insmod /lib/modules/2.6.31-18-generic/updates/alsa/snd.ko
  FATAL: Error inserting snd (/lib/modules/2.6.31-18-generic/updates/alsa/snd.ko): Unknown symbol in module, or unknown parameter (see dmesg)
  FATAL: Error running install command for snd
  
  dperson at argos$ dmesg | grep snd
  [15159.601963] snd: Unknown symbol unregister_sound_special
  [15159.602343] snd: Unknown symbol register_sound_special_device
  [15159.603482] snd: Unknown symbol sound_class
+ 
+ NOTE:
+ 
+ I listed my specific system, but believe the noted bug will stop any of
+ the backported alsa drivers from loading.
