Source engine based games don't use OpenAL, no. The onboard sound quality is more than likely dependant on the motherboard components, not just the chip.
Mrk, what system setup do you have? All the people getting the process_has_locked_pages BSOD are running Vista x64, 32-bit users don't appear to be affected. Have you tried running an OpenAL game under the XFi's game mode? (Bioshock, Stalker, BF2, Doom 3, Quake 4, OpenArena, etc).
I have Vista32 on q6600 and asus p5kc, xfi gamer.
i will pick up a game today i think, I have bioshock but damned if I am reinstalling that again.
I've been playing TF2 last night though and not had any issues but of course it's not OpenAL.
I will probably pick up Quake 4 on the way home from work.
Stay tuned!
It probably won't affect you then being on 32-bit Vista... going by all the people talking about the issue on the Creative forums, plus my own experience, it only seems to affect 64-bit users. Let us know all the same though![]()
