Hi.
It would be very helpful to paste a small test app (with code) that shows the
error. The only thing of note is that newer versions are more careful about
opening the capture device with the precise capture rate given (as the OpenAL
capture spec requires). This shouldn't break apps, though.. at least none that
aren't already broken.
It may be helpful to say which device is actually being used, by calling
alcGetString(device, ALC_CAPTURE_DEVICE_SPECIFIER);
on the opened capture device (for both 1.4 and 1.8). Would also be helpful to
know if PulseAudio is installed/active, or if you're using the aoss script.
