A new patch is at: http://people.freebsd.org/~marius/t4dwave_M5451_32-bit.diff This version now also basically works with the GENIALstation 777s, but there seems to be a problem with ac94(4) on that machine or it's wired strangely as I've to turn on the "PhoneOut" output in the mixer in order to get sound and its quality is likewise, though with the Blade 1500 all seems fine. If someone could test how far this patch gets things into working with Blade 100 that would be great. Marius
