Try adding the following two lines:

alias sound/* sb

I'm working on a sample database to be included with modutils. For
now, replace your serial aliases with:
alias tts serial
alias tts/* serial
alias cua serial
alias cua/* serial

Does it cause and problems?

It works for me. What are the symptoms you are seeing?

Don't worry about it. As the message says, only tell me about it if
there is a problem (related to the message, of course).

There is a section in the README/FAQ which talks about this.

Probably this is not a devfs-related problem. Do you get this problem
without the devfs patch?
