hi, if it is a new installation of ubuntu - it is the first audio application you try to start maybe the soundcard is allready in use by the desktop soundserver.

I had this problem running ubuntu and tried to start the jackserver - would have been the same for pd. When I started the jackd server via the qjackctl interface i got an error sayinng that the hw:0 (the first soundcard in my system) is allready in use. A Desktop like Gnome or Kde can run its own soundserver. So I had a look if Gnome's soundserver (esd, Kde is artsd) was running - and it was. So find the process and kill it :)

ps -auxwww | grep esd kill processnumber

# After that I was able to start the jackd server. #To make this permanent: # The startup of the gnome soundserver was stopped when I # disabled the startup in system-preferences-sound preferences. # And I could start the jack-server after it.

# btw: if you have also problems with the alsa sequencer. This is # what I found on the net about it:

# See if the snd-seq kernel module is loaded (as root): /sbin/lsmod | grep snd-seq # If it is not there, load it explicitly: /sbin/modprobe snd-seq # Try starting your application...

# loading explicetely worked fine for me.

hi folks.

i hope someone here has an idea of what's going wrong. i'm running ubuntu hoary 5.04 and i installed puredata via apt. i try running "pd" and nothing happens. when i run the command from a terminal, it just sits there with no result. eventually, i hit control-c and get "Pd: signal 2"

i also tried downloading and building from source, but have the same issue.

any ideas? i know it's hard without any error messages.

thanks, jake
