Hello all, I'm using gentoo, with kernel 3.17.0-p1-pf and at some point, a patch was included in this branch of the gentoo kernel that broke hdmi audio. I've checked with the latest 3.19 vanilla kernel, and I still have the same problem. I cannot output multichannel sound over hdmi. After some investigations, I've narrowed down the issue to the following lines in the file

Commits 0a9e2b959 (drm/nvd0/disp: move HDA codec setup to core) and a4feaf4ea (drm/nva3/disp: move hda codec handling to core) moved code around but neglected to fill data up to 0x60 as before. This caused /proc/asound/cardN/eld#3.0 to show eld_valid as 0. With this patch, that file is again populated with the correct data.
