Just FYI: As daveshah can now reproduce the issue on the uEVM, we're trying the original SDDK from TI. With old kernel, fully working AESS, etc.
If we can glitch it there as well, then we could still try to add the inverter - but adding the inverter to the 500 produced CPU boards would't be possible, I guess.
If it's not possible to glitch it with TIs older OS, it's likely we can somehow fix it.
What could be interesting is to compare the sound/soc/ti/omap-mcpdm.c driver as well as omap-abe-twl6040.c between v4.7 and v5.x. It is not even necessary to compare the letux versions since the old kernel does not have any private patches and we tested the newer one without letux (aess) patches.
It is a little more tricky to do that diff because the files have been moved to new locations.
