This is confusing as we can see messages about the baytrail-pcm-audio
device not being registered and then valid messages from said device ?
I'm wondering if you have created 2 baytrail-pcm-audio devices ? The
ordering is also confusing since the block allocation should come before
the DSP boot....

Can you paste the diff for all the audio changes you have made and also
the output of lsmod when this happens.

This date looks valid (meaning the FW has correctly booted) and also
like we are not getting the IRQ from the DSP.

This means we have not had a response from the DSP that it has completed
a command from the host. The IRQ is used to signal this too, so it's
possible that this is working on the FW side but the host is not getting
the IRQ.
