#243 sound doesn't work (on 0.5-pre4)

[Pierre FERSING]

With then 0.5-pre4 sound doesn't work (with LigthGui or
HeavyGui).

When I run alsamixer, a error say that he can't open
device (No such file or directory)
When I run modprobe snd_intel8x0, then module is loaded
but he say that install command fail.

I think the problem is that /dev is read-only (/dev/oss
or /dev/snd/* can't be created)
