I was trying last night to start pd from command line with the appropriate sound card selected. I tried pd -alsa -alsadev hw:1,0 and also replacing the space between the soundcard and the -alsadev with a = and :. On every case pd did not recognize the commands.
Recently I struggled with the same thing until I discovered the logic behind the ALSA device numbering. The option to use to select an ALSA soundcard actually is "-alsa -audiodev NUMBER". (I'm not sure if "-alsaadd" does anything at all.)
Now how to find NUMBER? Two rules:
a) it starts counting at 1, not at 0. b) Every physical soundcard found will result in two "-audiodev" numbers for ALSA: one hw-device and one plughw-device.
This is probably best explained with an example:
Assume you have two soundcards, e.g.
$ cat /proc/asound/cards 0 [M2496 ]: ICE1712 - M Audio Audiophile 24/96 M Audio Audiophile 24/96 at 0xf500, irq 11 1 [Audio ]: USB-Audio - USB Audio USB Audio at usb-0000:00:10.4-1.4, full speed
Then "-alsa -audiodev 1" will open hw:0, "-alsa -audiodev 2" will open plughw:0, "-alsa -audiodev 3" will open hw:1 and "-alsa -audiodev 1" will open plughw:1
