[PD] How do you start pd properly on Linux ?

I would like to use pd-0.37 under Linux (RH9/HDSP card), but I get strange
problems with it.
I installed the PlanetCCRMA rpm with apt-get.

ALSA driver works, for example I can play a sound with "aplay" (the only
backdraw is that "hdsploader" does not load automatically after booting)

When I type "pd" in a terminal, the pd windows starts, but I can't open nor
create any patch (Ctrl>n or Ctrl>o have no effect)
Actually, no GUI control has any effect, even Ctrl>q

I have to quit pd using "Ctrl>c" in the terminal, and I get this error :

Pd: signal 2
using non-interleaved audio input
Sample width set to 4 bytes
ALSA: set input channels to 14
ALSA lib pcm_hw.c:324:(snd_pcm_hw_hw_params) SNDRV_PCM_IOCTL_HW_PARAMS failed:
Device or r
esource busy
snd_pcm_hw_params (input): Device or resource busy
pd: pcm.c:4887: snd_pcm_sw_params_current: Assertion `pcm->setup' failed.
(btw nothing is printed in the terminal until I type "Ctrl>c")

any idea ?

When I type "pd -oss", pd has the same "phantom" behaviour

Maybe I should use Pd with JACK ? I will first read a good tutorial about JACK,
actually I know only very few about it

thanks for your help,
