Pharo Sound of Silence

64-bit Arch linux 3.17.6-1-ARCH

I seem to be running pulse-audio with alsa, and I believe I have all the 32-compadibility libraries installed, but my experience with linux sound is limited. What is Pharo expecting?

Thanks,
Evan

That did the trick. Thanks.

Hi,

I have written a chapter which explain how to have sound in Pharo.
You can read it here.

In fact all you have to do is to disable pulse-audio to make it work.
I have tested it with ubuntu 14.04 64, ubuntu 12.04 64, OpenSuse 13.2 64, sabayon 64 (don't remember the version) and should work for every distributions.

I think that should work for Pharo 4, but no time to test at the moment.

Hi,

We should discuss how to solve this. Neither "copy the squeak plugin", nor "disabe pulse-audio",
is a good solution.

The two methods can be used. But I think the best is not to use the plugin.
If the plugin is changing and is no longer compatible with Pharo or conversely you can no longer use this method. At the moment this is not the case.

While there, disable pulse-audio allows you to use Pharo with no change in its basic version. What seems to me to be less complicated in case of bugs on the sound system.

When writing the article for Linux Magazine (a French magazine) I asked myself this question. Should I write to use the Squeak's plugin or simply stop Pulse-Audio?

I put myself in the place of a newcomer in Pharo who wants to use the sound system. Install a plugin from elsewhere to run Pharo could give the image of a not finished tool. While there, the plugin does not exist and it does not matter because the sound works with a clear and simple method. It works out of the box.

After that, in a near future we should have a plugin for Pulse-Audio or best, Linux should have only one method to access sound, but it's another story :)

I'm trying to get sounds working in Pharo

If it helps, I started a minimal wrapper of the cross-platform FMOD library at http://smalltalkhub.com/#!/~SeanDeNigris/FMOD . I did enough to play mp3s.

( vm-sound-OSS is working too, and the source is already in the source tree)

OSS is just a pain to use today. Some apps doesn't even support it anymore. And if we want to use it with Alsa, an emulation layer must be installed. But it's not the point.

sound config
and kill the sound server"

No, this isn't better :)

I'm agree, it's not that way it should be done. But it's for me better than downloading another component to make it work, we could not know if it's fully supported or buggy.

In fact, there is a good way. Having a third part of drivers that are validated with Pharo. In that way, Pharo comes with just basic drivers to make it work and in another package we could have drivers that are validated with the stable version. If they don't work, we just have to email the contributor.

Pulse plugin will be in that last repo and if one day someone have some times to spend to include it in the source tree it will be great :)

We could have a documentation that explain how to include others drivers and let the user choice what is best for him. It's a good start to make Pharo even better :)

Really great ! i will try this on my linux box, thanks !

Could you add a bug report so that we add that to the list of esteban.

I don't know exaclty why we don't build the pulse audio plugin for pharo. But you can

take a squeak vm (Squeak-4.3-all-in-one) for example and copy the
Squeak-4.3-All-in-One/Contents/Linux-i686/lib/squeak/4.4.7-2357/so.vm-sound-pulse
in your pharo-vm directory
pharo-vm/vm-sound-pulse

after that, sound works at least on ubuntu 14.04 with latest pharo vm and image and pharoextras/sound package

I do not know either.
