Hi. I just downloaded the demo, and because this seems like it could be a pretty fun game, wanted to let you know about a bug I found. I'm running slackware 64 bit, and when I open the game it doesn't play any music. Sound effects are fine, but if I try to change the music volume, I get a segfault. I've included the last part of my console error messages, which are basically a loop of these 4 until I tried to change the volume, at which point you can see the segfault. I checked, and the file is where it should be, and can be played with other programs.

(hedSound.cpp)hedSoundManager::PLAY - (0)(hed-music/HEDuality-OST-time_is_up_-_duality.mp3)
(hedSound.cpp)hedSoundManager::PlayList_Play() - playing track (hed-music/HEDuality-OST-time_is_up_-_duality.mp3)
(hedSound.cpp)hedSoundManager::PlayList_Play() - error loading track (Couldn't read from 'hed-music/HEDuality-OST-time_is_up_-_duality.mp3')(0)
(hedSound.cpp)hedSoundManager::PlayList_Play() - error playing track (music parameter was NULL)
Segmentation fault

You need to have libSDL

Well I experienced nearly the same problems while having everything of the sdl libs installed on fedora.
To be precise, this machine runs fedora 16: 32 bit with the following kernel: 3.2.2-1.fc16.i686.PAE

The main problem is, that the mp3 music isn't played but all other sounds.
According to the rpm build - every depency is installed, except two:
libmikmod.so.2
libtiff.so.4

Well, they are installed but it's a different version. I just don't want to break all other depencies of programs.

Could this be the reason?

In addition there are some segmentation fault errors. They appear e. g. if I leave the actual game back into the main menu.
This happens not every time but there is a good chance that this error occurs.
-> I guess this happens because of the not playable music?

All in all I don't really have a clue what's going wrong.
I tried some symlinks from libmikmod and libtiff to my current versions, that if they want to use the never version they are redirected to the current one.
But it didn't work.

HEU runs flawlessly so far.

I uploaded the log flie on pastebin: http://pastebin.com/CiNtXADa
A small part (because the hedsound.cpp messages were looping) has been left out of the log due the size limitation on pastebin. It was between the segfault and the hedsound.cpp messages.

You need: libmikmod.so.2

Wrong answer.
Kinda weird if you found the problem yourself without any help of the devs but well...

First of all: The libs were installed like I said before.

The problem, why the music isn't played, is because mikmod doesn't have any module for mp3 files.
I checked it with "mikmod -n".
Don't ask me why (I don't have the knowledge about mikmod and there are _all_ depencies for hed installed) - all I can tell you this is the case!

How to solve it:
Everything can be found in the "hed-music" folder in the base directory of hed.
1. convert the .mp3 files into .wav (you could also try other formats, I just tested it with wav)
2. edit playlist text files: just rename every ending from .mp3 into .wav
3. everything runs fine and smooth
(at least for me)

Maybe there is a mikmod module for mp3s, then tell me please and I can try to add this one.
Is there any reason why the audio is delivered in the mp3 format? It would be much easier if for example ogg vorbis is used instead - it has also better quality while not exceeding the mp3 size.

Anyway it's working and there are no longer segmentation fault errors.

@DaZ: HED was designed with portability in mind and mp3 playback is common on all platforms.

I have to disagree here: while mp3 playback is certainly possible on every platform, it is not legal without a payed license everywhere and thus not available without manual work on platforms like Fedora. Had you chosen Ogg Vorbis instead, we would not have this problem. I made you aware of this way before the release of Duality because we had exactly the same problem on the previous Hacker game. You said it was too late to change there but would consider it for Duality. Sadly, you did not.

We went for mp3 for porting reasons (PC/Mac/iPad)
