As I finally managed to get sound working in DF v0.31.18 under Linux/KDE, I thought I'd post the instructions here for others to find.

As it happens, there were two problems.  The first was the DF wasn't loading the OpenAL libraries, giving an annoying dialog box and the following messages to the console:

Code: [Select]

Dynamically loading the OpenAL library failed, disabling sound
Initializing OpenAL failed, no sound will be played

Using the instructions from this thread, I solved the problem like this:

Code: [Select]

$ ln -s /usr/lib/libsndfile.so.1 df_linux/libs/libsndfile.so
$ ln -s /usr/lib/libopenal.so.1 df_linux/libs/libopenal.so

The second problem was that OpenAL was picking PulseAudio instead of ALSA as the output device, and failing for some reason like this:

Code: [Select]

Sound devices available:
PulseAudio Software
ALSA Software
OSS Software
Picking PulseAudio Software. If your desired device was missing, make sure you have the appropriate 32-bit libraries installed. If you wanted a different device, configure ~/.openalrc appropriately.
Initializing OpenAL failed, no sound will be played

Annoyingly, while the message suggests editing .openalrc, that doesn't actually do anything.   Apparently, that config file is no longer used in modern versions of OpenAL.  Or something.  What did work, however, was:

Code: [Select]

$ echo "drivers = alsa," > .alsoftrc

Now OpenAL is using ALSA, and I can listen to the relaxing plink-plonk of the DF theme to my heart's content.

you spent all this time trying to get sound working? in DF?

you do realize you could just play the music files, right?

[Cassicotca]

But its not the same thing  DF works now in linux as good as in windows?

[claer_runway]

also, and this might just be my experience, but the Linux version of df doesn't seem to be that well programmed. my fps is roughly the same just using WINE (in which it runs flawlessly)

Well done. Now turn the music off before the endless loop of the same track starts to annoy you.

also, and this might just be my experience, but the Linux version of df doesn't seem to be that well programmed. my fps is roughly the same just using WINE (in which it runs flawlessly)

This is because Wine only intercepts graphics and other system API calls (slowing them down), but doesn't touch the performance of anything the program does internally. The vast majority of the time DF uses is in internal code, slowing the graphics makes little difference.

[Cassicotca]

So almost as good as windows version or equal?

[trousermonkey]

Awesome!  Thank you.

I hate how audio is always such a PITA in linux.

I'm looking at you pulseaudio >_>

all which time? Oo

Thank you vyznev for guide, I'd like to post some comments and hope you edit first message to correct the tutorial.

Code: [Select]

$ ln -s /usr/bin/libsndfile.so.1 df_linux/libs/libsndfile.so
$ ln -s /usr/bin/libopenal.so.1 df_linux/libs/libopenal.so


For me (on Ubuntu) these files were in /usr/lib. It would be strange for libraries to be in /usr/bin

Code: [Select]

$ echo "drivers = alsa," > .alsoftrc


I think it's better to copy /etc/openal/alsoft.conf to .alsoftrc, and then uncomment and edit appropriate lines (a lot of info is in this file). I had a problem with ALSA stating incorrect periods argument, so I found it easier to choose OSS (which is still emulated through ALSA). Then there was another problem - after DF startup all other programs couldn't output sound.

If anyone could give a hint on solving any of these two problems (either with ALSA or with OSS), I'd be gratefull as well.

Code: [Select]

$ ln -s /usr/bin/libsndfile.so.1 df_linux/libs/libsndfile.so
$ ln -s /usr/bin/libopenal.so.1 df_linux/libs/libopenal.so

I got those two in my /usr/lib/ as well (arch linux).

my crappy, "this works so I haven't bothered to find a real solution" solution is to start youtube video in firefox, which also makes the other programs respect the alsa pcm volume.

I'd like to mention that Soundsense gives rather nice sounds for DF on linux because that is what I use. It gives you sounds for all the various events you have so you can hear when you hit a new type of rock or when someone is having their body parts sail off in an arc. I detail a couple things to make Soundsense run properly here http://www.bay12forums.com/smf/index.php?topic=60287.msg2170327#msg2170327

I can sympathize with Pulseaudio giving you problems having run killall pulseaudio one to many times but for me DF and pulse always seemed to get along. Windows unfortunately seems to lack any commands with the word kill in them.

Just a quick update for those running the latest version of Ubuntu (I'm running 12.04 now, should work for all who are still supported by Canonical).

To fix the problem make sure libopenal1 is installed

Code: [Select]

sudo apt-get install libopenal1
After which the library you're missing is /usr/lib/i386-linux-gnu/libopenal.so, so do the following

Code: [Select]

ln -s /usr/lib/i386-linux-gnu/libopenal.so /usr/lib/libopenal.so
if the sould still doesn't work, do the following in your game root directory

Code: [Select]

ln -s /usr/lib/i386-linux-gnu/libopenal.so libs/libopenal.so
And the sound should work
