Hello
We are trying to add a new ASOC card in our build that already contains an ASOC card.
We facing some issue when the second card is registered (calling snd_soc_register_card () ).
We can see in the log when playing a sound on the first card that second card operations are called.
In fact, the registration of second card overwrites the operations of the structure soc_pcm_ops of the first card (with the second card operations). Looking at the soc-core.c code, this structure is static so that explains the overwrite.
How can we register several ASOC cards on our platform in that case? Is it a bug or a limitation?
What kernel version are you using here. This shouldn't be an issue with recent kernels.

Thanks, Louis
