ALSA & Pulseaudio problem

[GeeZ]

I might have a solution for you (or at least a hint) :

I was able to switch from PulseAudio to Alsa by editing "~/.frictionalgames/Amnesia/MainDemo/main_settings.cfg" ;
on the last line you can change the number attributed to "Sound Device"
line 7 : "<Sound Device="0" Volume="1.000000" [...]"
It seams that :
- 5 is for pulseaudio
- 0 for default alsa

Now that I got my problem fixed, I was able to have a look in the Launcher's sound device selection menu, which is as of the following :
0 - default alsa
1 - alsa on ALC268 Analog (hw:0,0)
2 - alsa on Si3054 Modem (hw:0,6)
3 - OSS
4 - Portaudio
5 - PulseAudio
6 - Wave file writer
(NB: of course the numbers at the beginning of the lines are not indicated in the menu, I added them myself)
I guess that entry 1 and 2 are specific to my hardware (one for speakers and one for line out ???) and you might not have the same on your PC.

Changing the "Sound Device" parameter to the right number (3 on my PC) will do the trick. In my case (I had to get back to default Alsa), I put a "0" and it worked fine. However, if I try to force OSS on my computer, the game switches back to Alsa default, even if I select it using the GUI, so I can't tell you for sure if you'll make it work this way either.
