Drat - I'll have to go back to savng teh device by number in case the name isn't unique. Anyhow, it's the driver's fault I think.

As a workaround, give them ALSA names (which I think you can do using the ALSA config file somehow.) Me, I've never been able to understand ALSA.

hello,

i'm trying to use pd with 2 almost identical soundcard (edirol ua-1x and behringer uca222). They both works with aplay. On pd, the audio setting menu offer 2 "USB Audio CODEC", when selecting the 1st or the 2nd, only the 1st soundcard is used. so i can't select both on the same time.

i tried starting pd with pd -noprefs -alsa -audioadddev hw:1,0 but : Couldn't find audio input device: hw:1,0 i don't really understand what device name i should use for audioadddev option.

this works : pd -noprefs -alsa -listdev -audioadddev ""USB Audio CODEC"

but same result as changing the sound card in the menu : the 1st is always selected.

with : audio output devices:

1. HDA Intel PCH (hardware)
2. HDA Intel PCH (plug-in)
3. USB Audio CODEC (hardware)
4. USB Audio CODEC (plug-in)
5. USB Audio CODEC (hardware)
6. USB Audio CODEC (plug-in)

pd -noprefs -alsa -listdev -audiodev 5 will select audio dev 3

cheers c

...

So : how could i use 2 identical soundcard, and how to use the new audioadddev option?

using pd 46.6 / ubuntu linux 14.04

thanks cyrille

saving the device name is a nice functionalities. it's just that the 2nd card name should be : "USB audio CODEC #2"

i tried this : http://www.alsa-project.org/main/index.php/Asoundrc#Virtual_multi_channel_de... i was successfully using the "multi" device with aplay, but not with pd.

I think, "aliases" might work better here: http://www.alsa-project.org/main/index.php/Asoundrc#Aliases

The idea would be to define your own alias names for the USB cards like:

pcm.firstusb {
    type hw
    card 1
    device 0
}

pcm.secondusb {
    type hw
    card 2
    device 0
}

and then use

$ pd -alsa -audioadddev "secondusb"

But I've no idea if this actually works ... :(
