hi
sorry if this has been asked before. I am in the middle of a workshop and one student is having problems with the sound in PD, this is both with the latest extended version and the latest miller build
he is running a ppc g4 167gz on OSX 10.9
he is just playing a sine wave but the sound is dirty and periodically distorts (ones per sec or so). We tried not to load any externals, also increased the sound buffer, restart the machine, restart pd few times ... but keeps making the funny noise
i was wondering if anyone has experienced anything similar. we tried supercollider and MAX/MSP and both work fine.
thanks!

The GUI implementation under OS X isn't as streamlined as other platforms. So quickly refreshing GUI elements (like VU meters, etc) could be one source. For example, running another GUI-heavy app with PD can also cause this trouble.
I tend to use JackOSX, which gives me far less trouble than direct Portaudio. Portaudio could be one of those things (like ALSA on Linux) which needs some cleaning up.

actually he is using OSX 10.4.9 , i made a typo in first mail.
what you say is exactly what i thought, but we restarted the machine few times and it was always the same. he was not running anything else but pd. i also thought maybe it could be some driver problem, he has an external Edirol sound card he uses at home, here he was testing it with the built in sound card. maybe both drivers are present and PD goes funny?

I can vouch for what Derek is saying. Best to run Pd audio through Jack using JackPilot. This will smooth out your audio problems on OS X.

i see, but he has just started learning, he has used max a little bit in the past, i dont think he will go into using pd with jack, he is still getting into it, so he might just go back to max. I mean, i was using pd on mac for couple of years, i never had any problem like this, there might be another solution? I will try to talk to him tomorrow about the jack option and see what he says about it.
thanks

It's really pretty straightforward to do, even though it's annoying to have to load another program. This is definitely something that should be reported to the bug tracker!

if you really want to avoid having to open Jack each time, you can
use Autostart JackOSX from www.jackosx.com - the JackOSX manual at
that site is very complete as well. I find Jack is very much the
cleanest and most flexible way to handle audio on a Mac. If you also
want to route to different apps get QJackCtl from http://
qjackctl.sourceforge.net as well.

Yep, you may add jackd to your startup services quite easily (depending on your distro/platform), no need to launch via an application front.
It's a shame ALSA has become a bit ragged and neglected in recent times, I'm sure it will continue to mature and integrate with other audio layers, but for the time being I also strongly suggest Jack as the best option.
