How would we make Pd use that ALSA compatibility layer? I know about the OSS emulation in Pulseaudio, I believe that would work by doing 'padsp pd'.
padsp pd add to much latency, it is clearly unusable for pd.
on karmic, i have to set pd audio buffer to 400ms...

IIRC there is some sort of ALSA compatibility layer in Pulseaudio and I think it would be nice if Pd-extended could choose this ALSA "driver" or "soft card" or whatever it would be called. That would be a better solution than pasuspender because then Pd would be playing "nice" with all the other sound apps concurrently. Latency might be slightly worse but I think for beginners at least the initial experience would be more positive, as many of these users are coming from OS X and Windows platforms where sound applications sharing the same sound card concurrently is expected behavior.
I also vaguely remember the pulseaudio is only an issue with ALSA when there is no hardware mixer in the card. But my guess is that would be all cheap sound cards, since it has been the case with the built-in cards on all the Linux-based laptops I run into.

Is pasuspender something that could be integrated into the Pd-extended menu launch item somehow? I'd really like to make sure that Pd will output audio by just starting it in Debian/Ubunut. .hc On Nov 12, 2009, at 12:09 PM, John Harrison wrote:could be pulseaudio is the problem? from the command line try pasuspender pd On Thu, Nov 12, 2009 at 9:28 AM, Aditya Mandayam <adityams@gmail.com <mailto:adityams@gmail.com>> wrote: hi, i have pd installed on ubunty 9.10 - karmic koala. i have absolutely no sound when i fire up pd. i've tried fooling around with the Media>settings for OSS, ALSA, jack, default MIDI.
