    alcIsExtensionPresent

    Greetings all.

    I apologize if my post is more a rant/tirade than a cry for help but it is 06:02 in the morning and I'm less than happy at trying all the different "solutions" and not coming up with any gold!

    What happened was, about 8 months ago i had to re-install OpenAL32. When i had done this i got

    "Trials2.exe - Entry Point Not Found"
    'The procedure entry point alcIsExtensionPresent could not be located in the dynamic link library OpenAL32.dll'


    I thought this was just bye-the-bye and a "i'll do it later job" but i've finally exhausted all the offered solutions out there.

    Here's what i have done

    1. Are you running official video drivers? If not, that's the reason. (as posted by Mysterio) - YES & CHECK

    2. Did you allow the steam installer to install oalinst.exe to your computer? If you clicked cancel on that one, you can download the OpenAL installer from here: <LINK REMOVED> (as posted by sebbbi) - CHECK

    3. Also this file extracted to system32 directory has fixed the problem for some people in different games: <LINK REMOVED> But I highly suggest upgrading your audio drivers first. (as posted by sebbbi) - CHECK

    4. Have you tried to uninstall it all? Both the Trials game and the OpenAL? (as posted by 2k3) - CHECK

    5. Rename the following files in your system directory C:\Windows\System32: ct_oal.dll -> ct_oal.dll.backup, nvopenal.dll -> nvopenal.dll.backup - CHECK

    6. It seems that the OpenAl32.dll is a wrong version, it should be 6.14.357.22 (my version is 6.14.357.23) - CHECK

    Before anyone frustrates the situation further, all my Graphics & Sound drivers are all to-date.

    Can anyone just provide me a way to by-pass OpenAL32 or provide me a suitable solution? Or will this post be marked "DUPLICATE" like the others before me?

    I look forward to a response...

    I'm a bit tired at the moment, but here are some things you should try:

    - run the game with sounds disabled
    - try different sound card drivers (older ones)

    You could also try this:
    Never mind - I've sorted it now. I had to delete OpenAL32.dll from my System32 folder before installing OpenAL
    If none of those help, please tell me what hardware and operating system you are using (graphics and sound card are the most important ones)
