I have problem with HDMI and audio on my Asus AMD E-350 platform which started
around kernel 3.14 with sigle error message
"[drm:dce4_afmt_write_speaker_allocation] *ERROR* Couldn't read Speaker
Allocation Data Block: 0" which become even more severe with kernels 3.15 &
3.16 as now logs are flooded with "sound hdaudioC0D0: HDMI ATI/AMD: no speaker
allocation for ELD"

My setup is PC with Asus E-350 connected directly to the TV with HDMI cable (it
has been in the past to the 5.1 analog system hence the entry of "options
snd-hda-intel model=3stack-6ch-dig" in /etc/modprobe.d/alsa.conf)

on software side it is Gentoo with
libdrm & mesa & xf86-video-ati --- git versions updated on the regular basis
about every 1-2 weeks
pulseaudio 5.0
xorg 1.16.1
