[Newbies] Sound, video and color in morphic projects

I am Ricardo Salvador,  and i am writing because i found the solution to
one of the problems i asked for help about; maybe this will help someone

It's about sound playing. In ubuntu the sound was not played in morphic
projects and in the terminal I got the message "sound: /dev/dsp: No such
file or directory".
Since the "/dev/dsp" folder is part of the Open Sound System (which has not
been included in Ubuntu for a long time), for Squeak to find it, it was
resolved by installing "osspd" a package that emulates a daemon needed to
make the "/dev/dsp" folder available.
