I was just thinking about our example system with a DAC and the radio both connected to an amplifier. In that system - as it was - the amplifier was controlled by the DAC codec. Now to have on output for the analog radio the amplifier should be handled as a separate audio card, right? And then the analog radio and the analog amplifier could form a proper audio path. And the DAC would act as an output for the rest of the (digital) system and as analog input for the amplifier. Still correct? >> Are there any good examples that some of "us" should look into? > All ASoC drivers do this, it's a really basic part of the framework. > You can see examples of automatic management in the way the DACs and > ADCs are handled, and in the way the jack detection is integrated with > power management. Yes, but what I was in a way driving at was to find an example of a codec written for a purely analog device like the amplifier above. It would surely be different from normal codecs (or am I wrong)?
