Hello.

I have been working with pd-extended in Windows, not much, some basic things and this time I try to install for firt time Ubuntu 12.10 on my laptop.
After that, i install pd-extended from here: http://puredata.info/docs/faq/debian
I can install it without problems, but when i try to run it, the program say me this:

ALSA input error (snd_pcm_open): No such file or directory
ALSA output error (snd_pcm_open): No such file or directory

install the ALSA controler, and the error is again.

Try to change in "MEDIA" to the option "OSS" and the program say:

/dev/dsp (read/write): No such file or directory
(now will try write-only...)
/dev/dsp (writeonly): No such file or directory
/dev/dsp (readonly): No such file or directory
audio I/O stuck... closing audio

I too try to install pd-extended 0.43.4 from here: http://autobuild.puredata.info/auto-build/latest/ , but the same problem appears.

I hope you can help me. And sorry for my awful english.

Maybe not the best solution, but I'm using Ubuntu Studio, and it seems to work OK. Maybe looking into how to enable the packages related to studio might be helpful.

Hello! Did anyone manage to solve this? I'm having the same problem using Ubuntu 12.04

I get those errors if I switch to ALSA, but I've never tried to solve. I always have jack running and just use that instead. Haven't had any problems with it.
