Hi,

We have a question regarding how sound card can be registered for the following scenario:

CPU connecting to Audio CODEC_1 and then CODEC_1 connecting to another Audio CODEC_2 (over some bus like i2c). CODEC_1 can be represented as a codec_dai and can be registered to ASoC framework (with snd_soc_register_codec()) during system boot up. However, for end-to-end audio to work on this system, we also need CODEC_2 somehow registered to ASoC framework so that audio path on CODEC_2 can configured.

Could you please let us know if CODEC_2 can also registered as another dai and if yes, how it can be achieved ? Or is there any other way to probe_defer sound card registration till CODEC_2 is enumerated on the bus. In this case, to what component of the sound card dailink structure, the Audio CODEC_2 can be represented ?

Please share your thoughts on this.

Best Regards, Phani
