No LFE channel (subwoofer) in Ubuntu.

Do you have libopenal1 installed on your system? or are you using the included openal?

You can check this by looking at the libs64 folder in the amnesia game folder. of libopenal.so.1 is symlinked in there you are using the included openal. (it is symlinked from the all subfolder). Make sure to install your system openal (libopenal1 on Ubuntu) and rerun the checklibs64.sh script.

For full 3d audio support, openal itself has to support it correctly for your card, we are including an "older" version of the OpenAL-Soft implementation, which may not correctly support everything. The distribution version is newer so should yield better results.

If you are already using the distribution version, you can try upgrading to a newer version by downloading and recompiling it from http://kcat.strangesoft.net/openal.html
