I did some more experiments and I think that the bug should be reassigned to 
the kernel.

1) * Boot into the (bad) wheezy system
   # mount /dev/disk/by-label/squeeze-amd64 /mnt/tmp
   # mount --bind /proc /mnt/tmp/proc
   # mount --bind /dev  /mnt/tmp/dev
   # mount --bind /sys  /mnt/tmp/sys
   # chroot /mnt/tmp
   # aplay   /usr/share/sounds/alsa/Noise.wav
   Playing WAVE '/usr/share/sounds/alsa/Noise.wav' : Signed 16 bit Little
   Endian, Rate 48000 Hz, Mono
   
   ==> no sound.

2) * boot into the (good) squeeze system
   # mount /dev/disk/by-label/wheezy-amd64 /mnt/tmp
   # mount --bind /proc /mnt/tmp/proc
   # mount --bind /dev  /mnt/tmp/dev
   # mount --bind /sys  /mnt/tmp/sys
   # chroot /mnt/tmp
   # aplay   /usr/share/sounds/alsa/Noise.wav
   Playing WAVE '/usr/share/sounds/alsa/Noise.wav' : Signed 16 bit Little
   Endian, Rate 48000 Hz, Mono
   
   ==> sound plays.


Best regards,
