service/alsasound/cards can't find modules

Reported by:    mortimus

When trying to start `service/alsasound/cards`, it does not modprobe necessary drivers.

Fix:  REPLACE line 13 WITH

``` sh
for mod in `/sbin/modprobe -c | sed -n -e '/^alias pci:.* snd.*/ s/^alias pci:[^ ]* \(.*\)/\1/p' | sort | uniq`
```
