Hi Peter
The snd_pcm_hw_constraint_minmax() works fine when a single codec is connected to a single CPU DAI, but in multicodec or DPCM setup the constraints placed by the driver will apply to the whole PCM stream (FE included) and thus prevents more than 8 playback channels for example.

This patch breaks my sound. I'm selecting I2S between CPU<->Codec, and before this patch, it had been selected 24bit + I2S. But after this patch, it selects 16bit + I2S, and say "16-bit slots are supported only for slave mode using right justified"
Oops. I have sent a patch to fix this. Sorry for the inconvenience!
FWIW, I'm running one pcm3168a in CBS_CFS | RIGHT_J with parallel serializers (to one McASP) and other two also in CBS_CFS | RIGHT_J connected to a single McASP in parallel (so I can play 16 channel audio using the two).
I'm not 100% understand pcm3168a. I'm happy if you can solve this issue. If you can't, can you please teach me where should I check ?
Just sent a patch to fix the issue you are seeing with I2S mode (tested it myself).
Sorry again.
Thank you for your help !! Best regards
