Firstly, why?

I write it all myself because I don't know or trust auto generators much.

Of course that also means I have to be careful about formatting or I can end up confusing things even more as Paul encountered recently ;)

perhaps #include <asm/delay.h> is missing in some of pmac driver's
codes.  could you check the compile warning?

alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss

i tried some oss apps as well (pd, spiralsynthmodular). they don't
produce any errors, but theres no sound. 

and alsamixer has strange behaviour. the 'master' channel changes from a
mutable out channel to a 'captur' channel after a while ??
