[Pd] audio I/O stuck... closing audio

[ales at shark.mur.at]

well, it seems to work with :
pd -frags 5  -audiobuf 580 -alsa -nomidi
(i dont think [julien] you noticed i am having alsa)

but the sound is bad bad bad anyway.
i am looking for some external soundcard (usb) that is not using usb-uhci,
but usb-ohci . or anything cheaper.

cheers Alessq
