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
here are some logs. If more info is needed please let me know
