Dear All,
I've been working on a kernel patch for a firmware IRQ quirk issue that
affects multiple Intel Atom Bay-Trail boards:
https://bugzilla.kernel.org/show_bug.cgi?id=117141
If you have a Bay Trail device with non-functioning sound, can you
attach the DSDT and dmidecode output to the bug so I can investigate
whether the quirk affect your device.
Best Regards
Joel Holdsworth

The IRQ fix is not enough to get sound on Baytrail-CR devices. You need
to also swap SSP2 with SSP0 due to a package change, which is not
supported with the 'older' byt-rt5640 driver so that's a dead-end -
sorry. There are Intel patching coming for the bytcr-rt5640 to model all
the possible routing and quirks, stay tuned.
