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
