In KDE I play many sounds without issue. no problems.

I then want to play on puredata so I do

$ su
# /sbin/alsa force-reload -Rd alsa # reloads alsa system so KDE will release it for pd
# qjackctl
# pd

I'm using pd-extended and load my patch to play oggs. When I play one sound its fine, but if I'm playing 2 sounds then I get skipping or bad jittering :( it sounds terrible

it works under KDE so its not my kernel. I think its just bad setup that I have. I searched on google a lot but sorry dont know too much about these things.
