[PD] alsa : Invalid value for card

[Nicolas Montgermont]

Hello,

I'm using pd-0.47-1 on debian / jessie with an updated kernel (4.7.0.0)
with a scarlett usb card (solo this morning, will be 18i8 this afternoon...)
The card is working well in the system when I "test speakers"
the device appears well when i type "aplay -l"
with card number 1.
I don't have any integrated sound card, it is the only card.

I can't manage to make it work in pd,
it appears in the menu, but when I launch dsp, it shows:
ALSA lib pcm_hw.c:1667:(_snd_pcm_hw_open) Invalid value for card
ALSA input error (snd_pcm_open): No such file or directory
... same for output
what should I do to use it in pd?

Thanks in advance,
n
