Hi All,

I am pretty new to DirectX, but found some good tutorials relating to
DirectSound at VB2008. I followed along and was able to capture audio
from my microphone, but I want to capture the audio from the sound
card output (streaming internet radio for example). Is there a way
that the device capture can be turned towards the sound card data?

I use this call to populate my list of Devices to capture from, I
would like to specifiy the output data so I can grab the sound that is
being outputted from my sound card.

Microsoft.DirectX.DirectSound.DeviceInformation

IS this possible? Any thoughts?

Thanks,
Andrew

Hi,

If your sound card has a control name is "Wave Out Mix", "Stereo Mix" or something similar,
You are able to do it with mixer* Win32 APIs.

Manually...
1. Open the Volume control panel.
2. [Option]-[Property], then choose [Record].
3. Is there "Wave Out Mix" in a list of controls? Click a check box it.
4. Click [OK] then it will close.
5. Choose "Wave Out" as input device.

If you use Vista, this thread might help you.
