The audio driver supports all the audio features of the Videum card, including recording, playing, and all volume control and mixer functions. 32kHz, 44.1kHz, and 48kHz. It always uses 16-bit samples. It can use mono or stereo formats. Of course, you can use the audio features of the card simultaneously with video capture, including audio recording or playback.
All channels are stereo except the camera mic.
The record gain control and speaker volume have independent left and right controls, others have a single control that sets both left and right channels the same. The driver source file is wnvaud.c. Put this file in the sound driver directory. Now build modules. The driver does not work with all Videums.
