Thanks for the report. I'll try and find a system that can reproduce the
problem (up till now every soundcard / audio device I've tried has worked).

Re: [Openal] Capture problems under
I have done another round of testing. I tried three different capture test
programs: the first using the OPenAL32 DLL, the second using the wrap_oal
DLL (both the latest version) and the third using my own simple capture
library. (My library just opens the waveIn device and passes a buffer for
recording). All three programs have two subversions: one for 8000 Hz, the
other for 22050 Hz recording.
The result is conclusive: The test using my library worked w/o errors on
both machines I used. The other two tests gave identical results: on one
machine opening the capture device succeded but the number of captured
samples was zero. On the other machine they could not even open the capture
Based on these tests I would say that there is definitely a problem with
sound capture under Windows in OpenAL. I did this test at my workplace, I
could not yet try the test programs on my home machine (the only one on
which I could ever get any of the OpenAL capture tests working). If you
more data or want to see the code of the test programs, just let me know.
