1002:9589 [Gigabyte GA-MA790X-DS4] Video playback is like fast forward in 13.10 when radeon HDMI audio output is enabled

[Giannis]

The PC is connected to TV with HDMI cable. With Xubuntu 13.04 (3.8 kernel) no problem. With Xubuntu 13.10 (3.11 kernel) video playback is like set to fast forward speed. Is is happening both in browser video playback (Youtube) and video playback in Parole or VLC. Checked with or without radeon.dpm=1 and radeon.audio=1 settings. till 3.9.11 kernel, video speed is ok. from 3.10-RC1 bug introduced.

This issue appears to be an upstream bug, since you tested the latest upstream kernel. Would it be possible for you to open an upstream bug report[0]? That will allow the upstream Developers to examine the issue, and may provide a quicker resolution to the bug.

Please follow the instructions on the wiki page[0]. The first step is to email the appropriate mailing list. If no response is received, then a bug may be opened on bugzilla.kernel.org.

Once this bug is reported upstream, please add the tag: 'kernel-bug-reported-upstream'.

I found something very interesting. When I disable as default the radeon HDMI audio output from pulseaudio, video playback is normal again.

So maybe is related with the strange behaviour I have with kernel 3.11 and 3.12-RC4. HDMI is enabled whether or not I enable "radeon.audio=1" on GRUB but in both cases even though pulseaudio sound level output indicator inside "volume sound control" panel is showing "pulse", TV speakers doesn't produce any sound.

[John Reyes (john-a-reyes)]

Exact same with me. However, when I disable the HDMI audio, I am able to use the analog output and then sound and audio both function appropriately. - JAR

[Curtis Bissonnette (cjbissonnette)]

I am experiencing the same symptoms after upgrading from 13.04 to 13.10. When I select HDMI as my output sound source video and audo appear to play in fast forward. When using analog sound everything appears to work correctly. This was working correctly in 13.04.

[Giannis (karzisss)]

In my case I don't have HDMI sound at all.

[Giannis (karzisss)]

with xrandr --output DVI-0 --set audio auto I managed to re-enable audio actual output but video is still playing at fast forward.

[Curtis Bissonnette (cjbissonnette)]

I take it this will be fixed with https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1237530

[Giannis (karzisss)]

I did not see any fix when I installed this kernel. I don't think it will be fixed with this kernel.

[Giannis (karzisss)]

Update: I just tested 3.12 RC7 kernel. Sound output is fixed (doesn't need xrandr to be enabled but only "radeon.audio=1") but video playback is still "fast forward" like.

[Giannis (karzisss)]

till 3.9.11 kernel, video speed is ok.
from 3.10.0 and later there is this bug.

Tested it with kernel versions from http://kernel.ubuntu.com/~kernel-ppa/mainline/ with saucy (xubuntu 13.10)

[penalvch (penalvch)]

Giannis, the next step is to fully commit bisect from 3.9.11 to 13.10.0, in order to identify the offending commit. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection#Commit_bisecting_upstream_kernel_versions ?

[Giannis (karzisss)]

can't help you that far. Sorry.

[penalvch (penalvch)]

Giannis, could you please detail exactly where you are stuck in https://wiki.ubuntu.com/Kernel/KernelBisection ? It is written in a way so that if one is either a novice or an expert, they would be able to follow through to the end.

[Giannis (karzisss)]

from wiki: "The rest of this page assumes that you know how to fetch a kernel from the Ubuntu git repository, and build it, and that you have basic git skills"

Commit bisect (building a kernel) is NOT something a novice user can follow.

[penalvch (penalvch)]

Giannis, quoting from the wiki: " If you can't do that yet, try starting with this wiki page." -> https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel

how about vlc using hdmi:0 directly instead of pulseaudio ?

http://www.videolan.org/doc/vlc-user-guide/en/ch02.html

[Giannis (karzisss)]

on board hda is faulty. its not VLC only. Its the same on browser playback (both HTML and Flash) and Parole.

Giannis, thank you for performing the bisection. Could you please test the latest mainline kernel via http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.13-rc3-trusty/and advise on the results?

[Giannis (karzisss)]

I've tested 3.13-RC1 (there is no commit from Alex Deucher after this kernel) and bug is not fixed.

Possible fix: https://bugs.freedesktop.org/attachment.cgi?id=89768

[Giannis (karzisss)]

Bug fixed with Mainline Kernel 3.13-RC4

commit from Alex Deucher:
drm/radeon: program DCE2 audio dto just like DCE3

[penalvch (penalvch)]

Giannis, given a potential fix commit has been identified in mainline, I'll mark this Triaged.

[penalvch (penalvch)]

Giannis, the potential fix commit is now available for testing via http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.13-rc6-trusty/ . Could you please test this and advise to the results?

[Giannis (karzisss)]

Sound is working properly now with 3.13-RC5 already (commit was made in 3.13-RC4)

"drm/radeon: program DCE2 audio dto just like DCE3"

[Julian Wiedmann (jwiedmann)]

Giannis,
have you tried the latest kernel from saucy-updates (3.11.0-17.31)? It has the patch you mentioed in #30.

[Giannis (karzisss)]

Yes it is fixed.

[Peggys Mouse (peggysmouse)]

I'm having this same issue on 14.04 with 3.13.0-24-generic. Should I open a new bug?

[Peggys Mouse (peggysmouse)]

Thanks Christopher,

That's a lot of documentation to read through and I haven't installed an alternate kernel for a long time so it will take me some time to get this done. I likely will not be able to get back to this until next month.

PM.

[Peggys Mouse (peggysmouse)]

This seems to be working correctly for me after recent updates.
