ipchains and /dev/audio

["Christopher R. Barry" <cbarry@2xtreme.net>]

I just installed the 2.2.1 kernel over 2.0.36. I couldn't find
`/dev/audio' and `/dev/mixer' in the configuration options so sound is 
completely broken right now. What do I need to do to get `cat foo.au
/dev/audio' to work again?

Also, I use this WM dock-app called wmnet that used to use ipfwadm
which needed the "IP Accounting" kernel configuration option. I now
need to use ipchains to do this, but get always get an error like:

  ipchains: setsockopt failed: Protocol not available

I guess I need to compile something into the kernel that I'm not, but
what?
