Date: Thu, 01 Jan 2009 21:32:12 +0100 From: Couriersud Subject: Fusionsound audio driver attached is a diff containing a audio driver for the FusionSound library. This sound library is closely related to DirectFB and uses the same transport (fusion) as DirectFB when running applications "remote", i.e. over the network. As such, it natively redirects sound where DirectFB redirects video. This may be handy for everyone using SDL over DirectFB.
