[alsa-devel] About audio driver architecture

[Michael Qiu]

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?

Best regards
Michael Qiu
