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

--- Comment #1 from Alex Deucher alexdeucher@gmail.com --- 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.

--- Comment #2 from wmyrda wmyrda@auticon.pl --- 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?

--- Comment #3 from Sergei Sinyak serega.belarus@gmail.com --- 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 eld_valid 0
And hdmi codec

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.

--- Comment #4 from mirh mirh@protonmail.ch --- Created attachment 215621 --> https://bugzilla.kernel.org/attachment.cgi?id=215621&action=edit TV was attached before booting.
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=74... 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)

Created attachment 215621 [details] TV was attached before booting.
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/ ?id=7403c515c49c033fec33df0814fffdc977e6acdc I read this should be supposed to improve HDMI audio (it landed in 4.6-rc5).
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!
