Thanks. When trying to load the ALSA sound, stderr just reports "could not find module vm-sound-ALSA".

Doing an ldd on the vm-sound-ALSA.so included with the Pharo VM, I get:
�� linux-gate.so.1 =>� (0xf76e9000)
�� libc.so.6 => /lib/i386-linux-gnu/libc.so.6 (0xf7515000)
�� /lib/ld-linux.so.2 (0xf76ea000)

Doing an ldd on the vm-sound-ALSA.so included with the Squeak VM, I get:
�� linux-vdso.so.1 =>� (0x00007fffbdbfe000)
�� libasound.so.2 => /usr/lib/x86_64-linux-gnu/libasound.so.2 (0x00007f3c507ba000)
�� libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f3c503f3000)
�� libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f3c500ee000)
�� libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f3c4feea000)
�� libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f3c4fccd000)
�� librt.so.1 => /lib/x86_64-linux-gnu/librt.so.1 (0x00007f3c4fac4000)
�� /lib64/ld-linux-x86-64.so.2 (0x00007f3c50cca000)

There doesn't seem to be anything clearly missing.

Doing an ldd on the vm-sound-pulse.so included with the Squeak VM, I get:
�� linux-gate.so.1 =>� (0xf7721000)
�� libpulse-simple.so.0 => not found
�� libc.so.6 => /lib/i386-linux-gnu/libc.so.6 (0xf754f000)
�� /lib/ld-linux.so.2 (0xf7722000)

I did try to install the libpulse package (apt-get install libpulse-dev) but that file is still missing.

Weirdly enough, doing an ldd on the vm-sound-null.so included with Pharo, I get:
�� linux-gate.so.1 =>� (0xf774c000)
�� libc.so.6 => /lib/i386-linux-gnu/libc.so.6 (0xf757c000)
�� /lib/ld-linux.so.2 (0xf774d000)

which is the exact same thing as for vm-sound-ALSA.so. So, I would imagine that if the one worked than the other would.

Cheers,

Jeff

Hi!

If the modules are not printed, that probably means that they cannot be loaded :). (Bah, I assume that by looking at the vm code that does that [1]).

So, first thing you can do is to see the output of stderr. Second, you can try to do an ldd [2] to the vm-sound-ALSA.so library to check the dependencies and try to get them installed via ap-tget.

Keep us informed :)

Cheers,
Guille

Hmm. Did this get sent or was it filtered? It doesn't seem to be in my inbox for the pharo-dev list.

It arrived��

I'm using Pharo 2.0 on Ubuntu 13.10 and I can't seem to get sound working. Getting sound to work on Linux seems to be a common problem. While I've checked the archive for solutions, none of them work for me. I've investigated a bit and here's what I've found:

Inside of the /usr/lib/pharo-vm directory, I see the following:
vm-sound-ALSA.so
vm-sound-null.so
vm-sound-pulse.so (I added that based on an archive post that this would work)

When I do "pharo -vm-sound-null pharo.image", it works correctly.
When I do "pharo -vm-sound-ALSA pharo.image", it gives me an error that "could not find module vm-sound-ALSA".

When I do "pharo-help", I find that the only sound driver available is "vm-sound-null", though the others are clearly there in the directory. Is there anything I can do to make the VM acknowledge that the other files are there?

Cheers,

Jeff
