Ok, I think I've identified the incorrect bus_dma(9) settings
with the help of Tatsuo YOKOGAWA's ali(4) (which as least for
the alignment requirement also matches the NetBSD autri(4). 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.
