i think i got it

turn out that hidden ~/.pdsettings file allready consists audio settings for PD,and because i run my
patch from rc.local ,pure data takes configuration from that file
so eventualy when i do not use any commands when starting PD it is all fine and audio card is automatically assigned regardles of which usb port it is in

thank you anyways

thank you that seems very good solution
however
when i do pd -listdev my audio device and mididevices are on the same list
so if for example my usb audio is #2 and i unplug device #1 then usb audio becomes #1

this is why i thought audioaddoutdev will be best ,because this way PD knows exactly what to look for

hello everyone

i have this problem when using nogui PD with headless RPI
when i connect/disconnect usb devices to RPI ,my sound card "USB Audio CODEC " changes card number and my pd do not connect to it
i tried AUDIOADDOUTDEV with "USB Audio CODEC" and 'USB Audio CODEC' but that does not seems to work
any ideas?

thank you for clarifications

hello all

does anyone know if i can pass parameters when i create object pd
for example "pd test 12 13 14" ?

thank you

@whale-av
hello there
did you ever tried "audioaddoutdev -- add an audio output device by name" on linux ?
i had exact same problem on my RPI and PD to be able to alway use 'USB Audio CODEC (hardware)' whatever hardware card number it had.
i tried audioaddoutdev 'USB Audio CODEC (hardware)' ,audioaddoutdev "USB Audio CODEC (hardware)" ,but none seems to work

That makes sense, thanks! Though I'm having a hell of a time getting pd to load the hid external on the rpi. I've put the folder in /usr/lib/pd/extra and tried using the declare object but it just won't load...

i have spent entire day on this shit
here is what you need to add to PD command line,in my example was ELSE lib
-path /home/pi/Documents/Pd/externals/ -lib else
