| Is Openal support Multiple Input Device ? Is Openal support Multiple Input Device ?
If yes why the alcCaptureOpenDevice return NULL when the Device is Open ?
In fact i init Openal and when i try to record alcCaptureOpenDevice returns NULL. !!!
I must close the device and reopen it to record sound but sometimes i have error ""Unable toopen the device capture"

| What versions of the wrap_oal.dll and openal32.dll files are you using? Does your USB device support full-duplex mode (recording and playback simultaneously)?

| Thank you for your reply ...
I'am Using OpenAl Windows SDK
wrap_oal.dll ==> 2.1.8.1
OpenAL32.dll ==> 6.14.357.22
When i test my USB device from the properties of Sound and Peripheral I have got a message indicating that it's not support recording and playback simultaneously.
If that's the problem then how to solve It?
Thanks in advance |

| If your hardware does not support simultaneous playback and recording there is nothing that OpenAL can do to make it work - it is a hardware limitation of the device.
If you don't need to record and playback at the same time - then you could always do this sort of thing ...
When you need to play something ...
Stop and close capture device
open playback device, create context, set context current
play sounds
When you need to record something ...
Stop playing sounds, shutdown playback device and context
Open capture device and start recording
Depending upon what you are trying to do that may or may not be a suitable solution.
