Hi, i'm new on AllWinner but i have a couple of friends that have products/sbc with those soc. I'm designing a A33 board but i would know how the digital interface (pins) is multiplexed with the analog codec. I have read the datasheeet and also some drivers but it is still not clear to me.
- Is the digital interface indipendert from the analog codec? - Is the analog codec connected to the same i2s lines of the digital interface? The a33 have AIF1/2/3 but on analog codec driver i have found only ref to aif1 and aif2 and no aif3. What i'm interested in: - ANALOG playback via the inner codec (headphone output). - ANALOG recording via internal codec. - Lopping via AIF3 to playback. I have a bluetooth module hooked on aif3 for bluetooth audio stuff and FM radio. I would like to route the audio to the headphone output or to aif1 if I decide to use an external DAC. - DIGITAL playback via an external codec configured to have a prooper line out interface. This one could replace the first case (mutually exclusive with playback via headphones). If someone knows the audio layer and can descibe it to me is well apreciated.
