Perhaps that's what you're looking for? What processor are you using? There may already be implementations for it.

Hi, I'm going to write an audio driver for a developping soc used for dvb set top box. As I've never done such things before, so I've some questions.

1. Seems the "ALSA Driver Documentation" is mainly for PCI(and for PC)

based audio card. Where can I got a document for SOC which has no PCI bus. If there are some existing drivers it will be even better. 2. Is there any standard for such a audio driver which upper applications will depend on it? Or I can just follow ALSA?

If this is for an embedded system (sounds like it when you're talking about SoCs) then there's an entire subsystem for it under sound/soc with some documentation under Documentation/sound/soc

Use ALSA.
