The demo captures the audio stream from the selected audio
device.
Make sure that the "Audio Devices" from the "Options" menu in the demo is set to the audio device you want to capture from.

Hello
The "Audio Devices" from the "Options" menu have "None" and "SoundMax Digital Audio".
The "SoundMax Digital Audio" is selected. But still no sound.
Is there any other settings?
Thanks

The "SoundMax Digital Audio" is the name of your
sound card.
What is the name of the audio device that you are trying to
capture from? Are you trying to capture the audio from your sound card?

Hello
I am using external capture card (Pinnacle Systems 500 USB-Device). This is connected to the PC's USB port.
The input for this is a VCR. I am having only this option 'SoundMax Digital Audio".
I selected Capture Properties, in which there is a tab called 'AudioInput Mixer Properties'. There is a drop down called Pin Line, which has values CD Player, Line In, Microphone. But whatever I select, it says 'Format is not supported'.
I need to capture Audio, so that this part can be implemented in our application.
Any help on this is appreciated
Thanks

In some cases of capturing from a DV devise the audio and
video streams are sent as one stream from the capture devise.
Please try to set the audio device to none and try the
capturing issue. Does it work?

Setting Audio device to none is also not working.
I need to implement this capture functionality in my application soon. Please let me know other options.
Thanks

First, set the ltmmCaptureCtrl.UseVideoDeviceAudio Property
to TRUE. Then, set the selected audio device to 'none'. Finally, capture both
Video and Audio.
If this doesn't work, and you have the Microsoft Graph Edit
utility, use our EditGraph() method to see how the DirectShow graph is built
internally inside our toolkit. If you do that, can you send me a screen shot of
how the graph looks like?
