hey miller.
yeah on raspbian i got rid of the "invalid card" nag. no way to test stuff at moment via gui. all done via ssh on headless rpi.
my guess is it has nothing to do with pd. usb cards have to be set to default.
$ nano /etc/asound.conf
pcm.!default { type hw card 0 }
ctl.!default { type hw card 0 }
$nano /etc/modprobe.d/alsa-base.conf change line: # Keep snd-usb-audio from beeing loaded as first soundcard options snd-usb-audio index=-2
to: # Keep snd-usb-audio from beeing loaded as first soundcard options snd-usb-audio index=0

Well, first off, do you know about X11 forwarding in ssh? It's easy to run GUI programs over ssh and have all teh windows pop up on the calling machine. Just make sure /etc/ssh/sshd_config on the Pi has the line "X11Forwarding yes" (and restart sshd if necessary) and run "ssh -X" from the calling machine (-X might be on by default anyway; also you can change the default in /etc/ssh/ssh_configu). Type "pd" on the remote shell and bingo, the Pd window pops up on the calling one.
Sometimes there's an extra step to get permission to use the audio device on the remote machine if you aren't roo on it -- this can be done by adding your user account to group 'audio'.

Just FYI, on my RPI running raspbian Pd doesn't need a delay to turn the audio on, but does require a substantial buffer in order to work fine
with
the analog output.

it ends up that i forgot to do the delay on the loadbang thing to turn audio on with -nogui flag.
works but doesnt sound so good... ill work on that one...

Well, first off, do you know about X11 forwarding in ssh? It's easy to run GUI programs over ssh and have all teh windows pop up on the calling machine. Just make sure /etc/ssh/sshd_config on the Pi has the line "X11Forwarding yes" (and restart sshd if necessary)
and
run "ssh -X" from the calling machine (-X might be on by default
anyway;
also you can change the default in /etc/ssh/ssh_configu). Type "pd"
on
the remote shell and bingo, the Pd window pops up on the calling one.
Sometimes there's an extra step to get permission to use the audio device on the remote machine if you aren't roo on it -- this can be done by
adding
your user account to group 'audio'.

hey miller.
yeah on raspbian i got rid of the "invalid card" nag. no way to test stuff at moment via gui. all done via ssh on headless rpi.
my guess is it has nothing to do with pd. usb cards have to be set to default.
$ nano /etc/asound.conf
pcm.!default { type hw card 0 }
ctl.!default { type hw card 0 }
$nano /etc/modprobe.d/alsa-base.conf change line: # Keep snd-usb-audio from beeing loaded as first soundcard options snd-usb-audio index=-2
to: # Keep snd-usb-audio from beeing loaded as first soundcard options snd-usb-audio index=0

Hmm - no matter what I try over here I can't get Pd to complain 'Invalid value for card' - a lame guess would be that either the input or output only does mono and Pd is asking for 2 channels or something like that.
I suppose all works fine when you open Pd with a GUI, right?
Thanks for your patience... M
