Hi everyone, this project rulez !
Seems that the ROS sound system it's just on the way (check out the latest newsletter http://www.reactos.org/it/newsletter_20.html#sec6\), so a support from experts would be great.
ReactOS is an Open Source (GPL) effort to develop a quality operating system that is compatible with Windows NT applications and drivers (based on WINE's code).
HaPpY CoDiNg !
note: i haven't any relationship with the project (except that i'm the author of "open source software list" and "Hardware manufacturer's list" on the wiki).
update: I recently becomed the italian-section ROS forum moderator (forart.it).
