The driver has earlier been made public by Intel [2], and I've put my modifications to it here [3]. Unfortunately, it looks like the effort and hardware knowledge required to make this driver upstreamable is beyond what I can currently manage. Also, I cannot answer for whether or not other parties (such as Intel) plan to upstream the driver. -- David Henningsson, Canonical Ltd. https://launchpad.net/~diwic [1] http://www.intel.com/content/www/us/en/compute-stick/intel-compute-stick.html [2] https://github.com/01org/baytrailaudio [3] http://kernel.ubuntu.com/git/diwic/baytrail-hdmi-audio.git/log/?h=baytrail-T-hdmi-audio
