I always use -r 48000, maybe that helps

It could also be that this is due to the format, IIRC for DMIC you need 
to use S32_LE. I think we added some checks recently, and we did change 
the device names to make them self-explanatory.

I would try with the latest kernel (topic/sof-dev on GitHub) and 1.3 
firmware. We've done quite a few improvements for suspend/resume 
robustness and I am not sure they are all in 5.3. That error message was 
familiar a couple of months ago, I haven't seen it in a while. if it 
helps I can share the kernel config we use, you don't have to spend time 
recompiling useless stuff just to test audio. Also the autodetect for 
DMIC is not in 5.3, it was added later and is queued for 5.4

In terms of topologies, you probably want a recent version. Seppo added 
a filter to remove the DC component and boost the DMIC volume, the 
initial releases were 20dB too low. If this helps you can get the ones 
we tested at https://bugzilla.kernel.org/show_bug.cgi?id=201251, where 
DMIC issues were solved with others.

Soonish we will have packages and distros will be able to use stable 
releases and auto updates, please bear with the delays, the Summer has 
been quite busy.
