[Sound-open-firmware] Question about topology with mixer

[Daniel Baluta]

Hello everyone,

Is there any topology that mixes two PCM streams that
we can take as an example to start with?

We would like to do something like this:

PCM0 ----> volume ----------------+
                                                   |-- LL mixer ----> volume ---->DAI
PCM1 ----> volume ----> SRC --+

Also, should this result in 1 sound card with 2 sub devices, right?

Is there a plan to write a topology GUI tool? Writing m4 files
is not really easy 🙂.


thanks,
Daniel.
