Public bug reported: After upgrade from Xenial 16.04 to Yakkety 16.10, playing audio over HDMI no longer produces sound. * When booting with old kernel from Xenial (4.4.0-59), HDMI audio works fine * Audio from headphone jack works fine * Userspace seems to be happily playing to HDMI audio device, but no sound produced at HDMI sink (Samsung TV)
Any of a wide range of pre-built mainline kernels fail to produce HDMI audio, but with a different failure mode (HDMI audio does not seem to be enumerated in the same way as in the Ubuntu kernels.)
