Well, generally speaking, aoa only picks up machines it knows about
no ?
Actually, no. Since I have been building my own kernels, I have no
problems with snd-powerpc.
OTOH, many people on -powerpc has sent messages along the lines "I
just installed lenny/etch/squeeze/foo on my {Power,i}{Book,Mac} and I
can't get any sound, is there anybody here that can help me?".
It seems that on some G5 machines, snd-powerpc could cause some lock
ups, but the problem was reported ages ago and it seems to have been
fixed. I'm not sure if Charles Plessy (in CC) still has his dual G5
and can test it, but I seem to recall that he once had the problem
and, months latter, tested it again and didn't find any problems with
snd-powermac.
(Is this correct, Charles? My memory seems to be failing me lately.)
So, for a distribution kernel, I guess that, once nobody complains
about the problems, we can just standardize on snd-powermac (and have
people have a working setup) and document the potential (perhaps
nonexistent?) problem in the release notes for the arch.
I am willing to learn a bit about the kernel, but I don't have
knowledge about hardware.
Opinons?
Regards, Rogério Brito.
P.S.: Ben, are there low-hanging fruits in the kernel for PowePC on
Macs?
