drivers for dxr3-card

drivers for dxr3-card

[Christian Gmeiner]

Hi.

I am very new to alsa, but i want to write a driver for the dxr3 
(dxr3.sf.net).
At the moment there is only basic support through a patch for the 
current cvs. I want
know to add support for the digital output of the card - dolby digital - 
and add support
for ALSA OSS emulation.

So i have a very simple question, does Alsa support mutli-channel cards, 
e.g. for dolby digital?
Is there an example/dummy driver for multi-channel audio?

Thanks,
Christian Gmeiner

You don't need anything special for OSS emulation.  It's a job of ALSA
middle layer.

Sure :)

No dummy driver, but you can see different drivers like rme9652,
ice1712, ...  The codes strongly depend on the board/chip design.
