            Bug ID: 85241
           Summary: audio over HDMI on AMD E-350 with radeon driver
           Product: Drivers
           Version: 2.5
    Kernel Version: 3.14 and higher
          Hardware: All
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri@kernel-bugs.osdl.org
          Reporter: wmyrda@auticon.pl
        Regression: No

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

Are you actually seeing a problem with the audio playback or is this bug
strictly about the messaged in the kernel log.  If there is a playback problem,
can you bisect to indentify what commit caused the regression?  Also, please
attach files directly to this bug rather than using pastebin.  The messages are
due to your monitor not providing a speaker allocation block.  I think 3.14 was
probably the first kernel were we actually tried to query the monitor for the
speaker allocation block from the monitor.  The gfx driver passes this
information to the audio driver and the audio driver uses it to properly set up
the speaker layout.

I do have problem with the sound although it might not be an kernel bug at all,
but pulseaudio problem. For past several days I tried to pin point the problem
and found that this might be a problem with upgrade to xorg 1.16 and some
change that made my systemd startup script fail
https://bugs.archlinux.org/task/41391#comment125851 but problem persists even
when I do not try to run xbmc/kodi but gdm or lightdm as well. There is huge
(about 10min) delay before window manager start due to audio not being
initialized properly on the system where audio worked and now when it finally
starts without an audio. 

To summarize I am not sure is it kernel problem (with older kernel I just got
same issue), but seems be worth a check

PS. an errors in dmesg should play nicer anyways 

"sound hdaudioC0D0: HDMI ATI/AMD: no speaker allocation for ELD" could leave
just one message and be more explanatory too perhaps? What is ELD?

hi, i can reproduce this bug on two configurations.
That's radeon hd 6320, radeon hd 5650.
kernel version 4.1.3, but tried to load radeon module
compiled from 4.1-rc8, and it presents.

Description:
The actual question is that:
  after just loading radeon module
  there is no sound from monitor
  connected through hdmi wire.
  But after running gdm, or
  to be correct reinitializing driver
  with a help of Xorg based application
  everything comes back. But e.g.
  after suspend/resume cycle it
  again generates incorrect eld.
  As a result dmesg shouts
  NO SPEAKER ALLOCATION FOR ELD

Full text:

it generates eld file

$ cat /proc/asound/card0/eld#0.0
monitor_present        0

     0x02

As a result dmesg contains:
  snd_hda_codec_hdmi: "HDMI/ATI audio: No speaker allocation for ELD"

Won't describe the experience of such speaker, probably
it has no connection with a real problem.
I'll say only that after running Xorg i fix it.
In the following way changes appears:

In the codec file appears that line, and eld
file is filled with correct info.
P.S. i tried to fill eld file with a correct info
using possibilities of alsa driver, but no soudn.
Perhaps i should alter codec as well, or there are
still some missed work from the side of radeon driver.

TV was attached before booting.

I read this should be supposed to improve HDMI audio (it landed in 4.6-rc5). 

For as much as I have no problem with sound though, I'm still getting "no
speaker allocation for ELD" warnings. 

Also, I wouldn't know if the last EDID error is related or not (could just be
driver queried the interface before I could completely remove the cable)

Installed recently kernel update (4.7 now, previous 4.6.4). ELD speaker
allocation
is working without running Xorg this time.
Each time computer wakes up after a suspend I need to re-attach power cord,
otherwise
  $ cat f1/card0/eld#0.0
shows empty file. But botting up doesn't require reattaching of one.

Thanks to developers, one year old problem of mine had been partially fixed,
it's better then it was before!
