[Anmar Oueja]

Repro steps:

pre-requisites:
 - Laptop with working speakers. i am using Thinkpad X201
- Display with HDMI or Display port
- Speakers plugged into the Display

Steps:
- Ensure laptop is not connected to the display
- Play an audio file using Rhythmbox or Totem
- Audio should play fine from the laptop speakers
- Plug in screen and open the sound preferences. Notice the presence of Analog and HDMI/Display port outputs under the "output" tab.
- Analog should be selected

- Plug in screen via the HDMI or the Disiplay pot (I am using display port)
- Ensure speakers are plugged into the screen
- Swtich audio output to HDMI/Display port.
- Sounds no longer there

Expecte Results"

This makes HDMI audio work on Linux 3.2.x (0 <= x < 6).

My initial report of this issue can be found at https://bugs.freedesktop.org/show_bug.cgi?id=43947#c7 - this entry should take note of the fact that it happens for me on SNB, and not GM45.

I used to use a custom patch, baked for me by danvet, to make things work from 3.2.0 to 3.2.5. After switching to 3.3.0, I had to make use of another one, effectively pasting my old, working version over the current incarnation of intel_hdmi.c. I'll attached both patches to this bug for sake of completeness.

This is the fix I use on 3.3.0.

[Luke Yelavich (themuso)]

Please get a log from PulseAudio, as per https://wiki.ubuntu.com/PulseAudio/Log.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Bernie Innocenti (codewiz)]

Probably this bug: https://bugs.freedesktop.org/show_bug.cgi?id=48266

If confirmed, component should be changed to kernel.

> This is the fix I use on 3.3.0.

I tested this on a custom compile of the Ubuntu kernel 3.2.0-23-generic, which is based on vanilla 3.2.14.

I didn't notice any difference in behavior: sound works on the analog output, but not on any of the 3 HDMI outputs. This is with a DisplayPort cable on a Lenovo X200 (Sandybridge).

[colo (johannes-truschnigg)]

The Lenovo/IBM Thinkpad X200 contains a GM45 IGP, not a SNB one. I know, because I am sitting in front of one right now :)

It' feels good to read that I'm not alone with the problem though. Apparently, the problem isn't limited to one gen of IGPs.

[Daniel-ffwll (daniel-ffwll)]

Johannes, to avoid further such goof-ups, can you please attach the full dmesg with drm.debug=0xe on the kernel cmdline?

[David Henningsson (diwic)]

Lowering severity since this seems to be a hardware dependent problem, not a generic one.

[Anmar Oueja (anmar)]

I understand the importance lowering but why mark it as incomplete? what else do you need to make it "complete"?

[Mathieu Trudel-Lapierre (cyphermox)]

I believe what's missing is the PulseAudio logs, as requested by Luke; see http://wiki.ubuntu.com/PulseAudio/Log.

I'm linking the related freedesktop bug, and since it contains a kernel patch it probably belongs being looked at by the kernel team as well.

[Mathieu Trudel-Lapierre (cyphermox)]

Kernel Team: As mentioned above, please see the related pulseaudio bug, it contains a possible patch that might help mitigate the issue, though it doesn't appear to have received review from upstream kernel.

[Paulo Zanoni (pzanoni)]

Hi

Could please try the 9 patches from the following link: https://bugs.freedesktop.org/attachment.cgi?id=60529 ?

I believe patch 1 should fix the problem. If you have some time, you could do
two tests:
- one test containing only patch 1 applied
- another test containing all the patches applied

If patch 1 fixes the bug by itself, the plan is to submit only patch 1 to
stable, but submit all the 9 patches to the development branch.

Thank you,
Paulo

This bug is missing log files that will aid in diagnosing the problem. From a terminal window please run:

apport-collect 973704

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

I built a precise test kernel with patch 1 from the upstream bug[0]. It would be great if folks affected by this bug can test the kernel, which can be downloaded from:

Ok, given that this bug is also about gm45 (and not snb as I've originally thought), I presume it's also fixed by the gen4 infoframe fix merged into drm-intel-fixes:

    drm/i915: enable dip before writing data on gen4

    While testing with the intel_infoframes tool on gen4, I see that when
    video DIP is disabled, what we write to the DATA memory is not exactly
    what we read back later.

    This regression has been introduce in

    commit 64a8fc0145a1d0fdc25fc9367c2e6c621955fb3b

        drm/i915: fix ILK+ infoframe support

    That commit was setting VIDEO_DIP_CTL to 0 when initializing, which
    caused the problem.

[Sebastien Bacher (seb128)]

upstream has a fix commited:

" drm/i915: enable dip before writing data on gen4

    While testing with the intel_infoframes tool on gen4, I see that when
    video DIP is disabled, what we write to the DATA memory is not exactly

[Julian Wiedmann (jwiedmann)]

Anmar,
please test the latest kernel from precise-updates (3.2.0-25.40) and see if this issue persists.

(hopefully fixed with 'drm/i915: enable dip before writing data on gen4')
