I have made a testimage with the patch I want to include in the next LE release. It would be nice if someone could verify that it works.
Index of /Test/8.2/ <- this bases at an early LE8.2 build so better do a complete backup before the update (8.2 has no working plugins yet), you will also need a "new" Tvheadend version that runs at 8.2 (both included).
Thanks CvH! I setup an ASUS chromebox2 to run Kodi for the first time. I also was failing to get the Wintv-Dual to work. I reinstalled the OS using the image you provided and now all works well. I guess this means I have validated the image for an x86 platform? Thanks again for providing this, I thought I would have to wait several weeks for the official 4.12 release.
