Sound with lots of latency is better than no sound at all.
i don't think so. no sound -> you realize that there is a problem that need to be fixed. big latency -> you think ubuntu / pd is crappy.
Here's how I see it now:
- pd currently doesn't make sound on Fedora/Debian/Ubuntu without
changing settings
well, it depend of your sound card i think. mine work perfectly with oss, so i did not have to do anything to have sound. as long as i don't use other audio software.
- newbies are screwed, no sound output
- advanced users already setup their own audio
i did not set up anything.
So if we use padsp by default, we get this, which seems preferrable to me:
- pd makes sound on Fedora/Debian/Ubuntu without changing settings
- newbies get sound with lots of latency
- advanced users already setup their own audio
we will have lot's of mail in this list asking why pd can't make a sound with less than 500ms latency, and i'll answer : "pd extended configuration is crappy"
Even better, you could get sound from Pd and other apps at the same time. If there is a way to get to the second status without big latency, that would be the best.
yes, that would be the best. but i did not find any solution other than installing jack or maybe having pd to use pulse audio...
'padsp' is the only trick I know of, I haven't tried pasuspender tho.
pasuspender work great, as expected : it stop other applications from using the sound card so pd can have full control of it. and as soon as pd stop it gives back the sound to the other applications...
padsp is definitly not a good solution, pasuspender is the way to go i my opinion.

padsp pd add to much latency, it is clearly unusable for pd.
on karmic, i have to set pd audio buffer to 400ms...

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'. .hc On Nov 13, 2009, at 11:28 PM, John Harrison wrote:
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.

hi, i have pd installed on ubunty 9.10 - karmic koala. i have absolutely no sound when i fire up pd. i've triedfooling around with the Media>settings for OSS, ALSA, jack, default MIDI.
No sound. What gives?
