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

iirc, there's a problem if the cards are not in consecuritve order, starting with 0.
e.g. my devices are $ cat /proc/asound/cards 0 [DSP ]: H-DSP - Hammerfall DSP RME Hammerfall HDSP 9652 at 0xf3100000, irq 22 1 [MID ]: HDA-Intel - HDA Intel MID HDA Intel MID at 0xf3420000 irq 33 2 [NVidia ]: HDA-Intel - HDA NVidia HDA NVidia at 0xf3000000 irq 17 $ which means i have 3 devices with ids 0,1&2.
if however, you have something like $ cat /proc/asound/cards 1 [NVidia ]: HDA-Intel - HDA NVidia HDA NVidia at 0xf3000000 irq 17 $
then you are missing the device #0, and Pd gets into trouble.
a couple of workarounds:
- use jack to talk with the soundcard, so Pd doesn't need to know
- make sure that the card numbers start with 0 (and are consecutive, in
case you want to access a not-first card); this most likely involves tweaking some kernel module parameters (for the soundcards to be loaded), and maybe some udev rules.

thanks for fast and precise answer editing /lib/modprobe.d/aliases.conf and changing: options snd-usb-audio index=-2 to options snd-usb-audio index=0 make the card number to 0 and works in pd with alsa. n
