Hi, I tested SoundBlaster live! 24-bit on FreeBSD-current (Jan. 27, 2005). Result: it can record in 16-bit, but can't do in 24-bit. And it can't play any source. In the case of released FreeBSD, FreeBSD-stable and FreeBSD-current before Dec. 25 2004, they don't have recording systems for USB audio devices, and I guess that it can't play in the same way. These source code for USB audio devices come from NetBSD. So I also tested it on NetBSD and I got the same result as FreeBSD-current. I conjecture that this failure results from disagreement between BSD source code and 5.1 ch sound. So I recommend to use a simpler USB device of 2 ch and 16 bit. I use SoundBlaster Digital Music (not LX, PX), and it can play sound sources on old FreeBSDs, and can record on FreeBSD-current after Dec. 25 2004. Kazuhito HONDA
