Help text

This is a video4linux driver for direct (DMA) audio on Conexant 25821 based capture cards using ALSA.

It only works with boards with function 01 enabled. To check if your board supports, use lspci -n. If supported, you should see 14f1:8801 or 14f1:8811 PCI device.

To compile this driver as a module, choose M here: the module will be called cx25821-alsa.
