 Activities can modify sound mixer levels, and these are saved on shutdown
 because /etc/init.d/halt calls salsa.

 We have seen a number of cases where laptops have broken sound because PCM
 is muted and at 0 volume.

 In Paraguay we will work around this by copying the stock asound state to
 a non-standard filename and hacking olpc-configure to restore from that
 special file during boot (if an activity screws up sound, then a reboot
 will fix it).
