Savolainen. Savolainen made the code available under free software licenses, GPL for Linux and BSD for BSD distributions. Between November 1993 (and Linux 1.00) and 1997, OSS was the sole choice of sound system in FreeBSD and Linux. This was changed when Luigi Rizzo wrote a new "pcm" driver for FreeBSD in 1997, and when Jaroslav Kysela started Advanced Linux Sound Architecture in 1998.

In 2002, Savolainen was contracted by the company 4Front Technologies
