The problem is getting things working for newbies. This has never
worked for me, but I haven't tried Karmic yet:
i don't think karmic will make any diference.
- install default Ubuntu setup
- install puredata.deb or pd-extended.deb
- launch pd using the GNOME menu item
- then check sound
This works on Mac OS X and Windows. I am guessing that you don't run
pulseaudio, so that is a non-default config.
i do run pulse audio.
when pulse audio don't use the sound card, pd can use it.
the only modification to the audio configuration i'm doing is removing ubuntu
sound.
I still think a crappy
working config is a better default than a non-working config.
what is the problem with pasuspender?
you can't watch youtube video when using pd, but pd should always act normal.
so, pasuspender is crappy, padsp is very crappy...

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'.

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 tried
fooling
around with the Media>settings for OSS, ALSA, jack, default

No sound. What gives?
Thank you,
