I have a sound card with a CM6631A audio chip running UAC 2.0.
There are 2 analogue sub devices on the chip both of which should support
S32_LE, however I do not see the S32_LE alt setting for one of the outputs.
lsusb -v, I see the following for each output:
Interface Descriptor:
Hi,
I need to implement a rate converter after dmix, means dmix will mix 3
channels as input, and the output will be of 48KHz, but then i need to
convert it to 96KHz output and send to HW.
How this can be achieved, seeing that we can't have a plugin after dmix.

No; the dmix plugin requires direct access to the hardware device's
memory buffer, which is not part of the plugin API.
