[LAU] snapper people do not have alsa after all?

am on iBookG4 have Slackintoh,DebianPPC(stable&unstable),UbuntuPPC7.04 on it only Ubuntu made sound without doing manual fix at this moment all of the are using its distro's default kernel(non-low-latency) jack related things never worked if i had -dalsa in the jackd line and at last i found out that jackd -R -doss -r48000 -p1024 -n2 would (kind of) do the job could play chuck things on Debian&Ubuntu but now wondering what this "only -doss works" aspect mean and result into maybe what we have is oss that is doing fake alsa? then we cannot have several apps making sounds at the same time via jack? on Slackintosh had to put this in /etc/modprobe.d/alsa: alias char-major-116 snd alias char-major-14 soundcore alias snd-card-0 snd-powermac alias sound-slot-0 snd-card-0 alias sound-service-0-0 snd-mixer-oss 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 alias /dev/mixer snd-mixer-oss alias /dev/dsp snd-pcm-oss alias /dev/midi snd-seq-oss options snd cards_limit=1 then most of the things work like as if alsa is there but the alsa version of chuck claims about sound device and the oss version of chuck gives an segmentation error jack version of chuck seemed to do okay with -doss but with no sound on Debian had to put "snd-powermac" in /etc/modules and choose "alsa" as default sound device in /ect/libao.conf with already having this in /etc/modprobe.d/alsa-base: -----8<--- # Cause optional modules to be loaded above generic modules -----8<--- install snd-portman2x4 /sbin/modprobe --ignore-install snd-portman2x4 $CMDLINE_OPTS && /lib/alsa/mod probe-post-install snd-portman2x4 install snd-powermac /sbin/modprobe --ignore-install snd-powermac $CMDLINE_OPTS && /lib/alsa/modprob e-post-install snd-powermac install snd-pxa2xx-ac97 /sbin/modprobe --ignore-install snd-pxa2xx-ac97 $CMDLINE_OPTS && /lib/alsa/m -----8<----- on Ubuntu didn't even have to do alsaconf while doing alsaconf didn't work properly on other distros -- 2g http://micro.ispretty.com
