Amnesia: Through the Portal (2.0 Expansion Released)

[Joseph Curwen]

I tried getting it to run under linux, but it keeps crashing with a segmentation fault. I run
'./Amnesia.bin config/ttp_main_init.cfg'
then the screen resolution changes for a moment and it crashes.
Messages in terminal are:

jack server is not running or cannot be started
bt_audio_service_open: connect() failed: Connection refused (111)
bt_audio_service_open: connect() failed: Connection refused (111)
bt_audio_service_open: connect() failed: Connection refused (111)
bt_audio_service_open: connect() failed: Connection refused (111)
Cannot connect to server socket err = No such file or directory
Cannot connect to server socket
[Stuff above repeated three times]
jack server is not running or cannot be started
Segmentation fault.

When I launch it with the original 'main.cfg' file, it does not crash, but also complains about the jack audio server not running.

Has anyone had the same problem and can tell me how to solve it?
