[Openal] No OpenAL devices found for SigmaTel integrated audio

[Daniel PEACOCK]

Hi Tim,

I'm not sure why linking with openal32.lib vs using LoadLibrary and
GetProcAddress would make a difference.   I don't have a SigmaTel
integrated chip to test here - but maybe a good experiment would be to
modify an SDK example to link with openal32.lib instead of using
LoadLibrary and see if you can reproduce the problem.

Ah, that’s rather curious.  Yes the OpenAL SDK examples work just fine.  A
single Generic Software device is enumerated.

The main difference between my code and the examples is I’m not using
LoadOAL, just linking to the OpenAL32.lib.

And no we haven’t updated the drivers.  We’re trying not to have to update
the audio drivers, since this platform is in already in use at multiple
locations.

The computer is a Dell Dimension 9200 using SigmaTel integrated audio.  It
correctly plays sounds in applications and games.  I installed the latest
OpenAL version available (summer 2007).  The device enumeration extension
is available and reports 0 devices.  If I still attempt to query “Generic
Software” or “Generic Hardware”, alcOpenDevice returns NULL.  I don’t get
any OpenAL errors.

Any ideas?

Hi, Tim,

Have you updated your audio card drivers recently?

Did you install the OpenAL 1.1 SDK, or just the run-time?  If you installed
the SDK, do any of the examples work?
