First of all, make sure you have unzipped the file in the right location - it should be in the game INSTALL dir (not the logs/settings dir), in other words you should have a folder "sound" in the same directory as other folders "2dobjects", "3dobjects" ... "textures". And, "sound" should contain directly the various .ogg files, not another subdirectory. Once this is checked, ...
This might be a problem with your audio subsystem. Traditionally, under Linux (and other Unices) you can just output audio data to /dev/dsp and have it played for you; however opening the audio device also locks it, so only one process at a time can access the audio. This has been solved in two ways: by providing a master daemon to mix audio from multiple sources (as in esd or alsa), or by offering a different kernel-level interface (as in oss). It is hard for me to tell what you have on your machine, since I am not on Ubuntu.
However, you can look for some compatibility layer. This could come either as a system-setting, or can be forced on the command-line. For example, running
aoss eternal-lands
ensures that eternal-lands is executed in an environment where the alsa-oss compatibility layer is activated. Another option is of course to see if you have another program locking the audio device and kill it, but this might make it impossible to mix audio from eternal-lands to that coming from other sources (say, your favourite battle music in the background ). Let us know if you make any progress. Also, someone with Ubuntu 10.10 might be able to provide more precise help.
I was having a similar problem with the sound, but after installing and running the game with the aoss command I have sound. Unfortunately, when I quit with alt-x or alt-q the .bin runs one of my cpu cores to 100% and the picture freezes. I have tried running the game without aoss and sound turned off and it exits cleanly. Is there a better way to exit the game or an option for the aoss command that will ensure a clean quit? Thanks!!
