--- Comment #2 from Nicolai Hähnle nhaehnle@gmail.com --- Hi Aaron, thanks for the traces. The playback of both traces looks fine to me on Tonga. So either this has been fixed very recently, or it's SI/Oland-specific.
I'm curious, could you please post your dmesg and the output of sha1sum $(find /lib/firmware -iname *oland*)?
