I noticed it once, too, but I had no time to check further.
More interestingly, PA works fine when LPE audio is the single driver
(i.e. blacklist Intel SST instead), too.  So it's more likely a bug in
PA.

What happens when you modprobe LPE audio driver after starting the
session?  If it kills PA, we can debug more easily :)
