Bug description:
  After upgrade from Xenial 16.04 to Yakkety 16.10, playing audio over HDMI no 
longer produces sound.
  * When booting with old kernel from Xenial (4.4.0-59), HDMI audio works fine
  * Audio from headphone jack works fine
  * Userspace seems to be happily playing to HDMI audio device, but no sound 
produced at HDMI sink (Samsung TV)

  Any of a wide range of pre-built mainline kernels fail to produce HDMI
  audio, but with a different failure mode (HDMI audio does not seem to
  be enumerated in the same way as in the Ubuntu kernels.)

2017-03-22 Thread Kai-Heng Feng

Do you have any alsa/pulseaudio config?

This can be quickly verified by running "vanilla" Ubuntu.

16.04: http://cdimage.ubuntu.com/xenial/daily-live/current/
17.04: http://cdimage.ubuntu.com/daily-live/current/

If both of them work, then it's probably related to your config setting.

[Kernel-packages] [Bug 1657994] Re: Regression: HDMI audio produces no sound (Skylake NUC)

2017-03-18 Thread Joseph Nuzman

I had been trying to cherry-pick patches from the working Xenial kernel
to mainline, and got bogged down with build issues.  Back to the
bisection:

This kernel ...
http://kernel.ubuntu.com/~jsalisbury/lp1657994/linux-image-4.4.0-040400-generic_4.4.0-040400.201702021530_amd64.deb
.. does not work.  Failure mode like 4.4 mainline.

I can also update that mainline kernels 4.10.3 and 4.11-rc2 both fail
like other recent mainline kernels.

To recap, we have only two working data points, both Xenial kernels (4.4+i915 
backport).
4.4.0-59
4.4.0-21

All mainline 4.4 kernels do not even enumerate HDMI audio.

All mainline kernels from 4.5-rc1 and later enumerate HDMI audio but
produce no sound.

[Kernel-packages] [Bug 1657994] Re: Regression: HDMI audio produces no sound (Skylake NUC)

2017-02-14 Thread Ian Bruce

I would like to add some information to this bug report, which may or may not 
be relevant.
There seems to be a general problem with HDMI audio in recent kernel versions.
I am using Debian kernel packages, on an AMD64 system with a Radeon R9-280 
video card:

01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] 
Tahiti PRO [Radeon HD 7950/8950 OEM / R9 280]
01:00.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Tahiti HDMI Audio 
[Radeon HD 7870 XT / 7950/7970]

My experience has been as follows:

Linux v4.6.4 -- HDMI audio works

Linux v4.9.2 -- HDMI audio works

Linux v4.9.6 -- HDMI audio does not work

There were also problems with kernel versions 4.7 and 4.8. I had the impression 
that
it was intermittent; sometimes when the audio did not work, a reboot or power 
cycle
into the same kernel version would make it start working. It appears that with 
my
hardware, Linux v4.6 was completely reliable; more recent versions are 
substantially
less so, or even completely broken. (I'm not exactly sure whether v4.9.2 always 
worked,
or only most of the time.)

I hope this information is useful in locating the specific source of the
problem.

[Kernel-packages] [Bug 1657994] Re: Regression: HDMI audio produces no sound (Skylake NUC)

2017-02-02 Thread Joseph Salisbury

We are bisecting between those two kernel versions to identify the
commit that introduced this regression.  Some of the test kernels I post
will be bad and some will be good.  At the end of the testing the bisect
will point to one particular commit.

I built the first test kernel, up to the following commit:
aee3bfa3307cd0da2126bdc0ea359dabea5ee8f7

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1657994

Can you test that kernel and report back if it has the bug or not? I
will build the next test kernel based on your test results.

Thanks in advance

[Kernel-packages] [Bug 1657994] Re: Regression: HDMI audio produces no sound (Skylake NUC)

2017-01-31 Thread Joseph Nuzman

For this kernel, no audio.  Failure mode is like 4.4 mainline.

Just to understand:  the strategy is to bisect between two mainline
kernels with different failure modes (4.4 final and 4.5rc1), with the
hope that between the two there will be a good kernel?

[Kernel-packages] [Bug 1657994] Re: Regression: HDMI audio produces no sound (Skylake NUC)

2017-01-31 Thread Joseph Salisbury

I started a kernel bisect between 4.4 final and v4.5-rc1. The kernel
bisect will require testing of about 7-10 test kernels.

I built the first test kernel, up to the following commit:
1289ace5b4f70f1e68ce785735b82c7e483de863

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1657994

Can you test that kernel and report back if it has the bug or not?  I
will build the next test kernel based on your test results.

Thanks in advance

[Kernel-packages] [Bug 1657994] Re: Regression: HDMI audio produces no sound (Skylake NUC)

2017-01-31 Thread Joseph Salisbury

Can you test the 4.4.0-21 kernel next:
https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/ppa/+build/9594168

If it is good, we can bisect between 4.4.0-21 and 4.6.0-10.

Both kernels behave like any of the kernels from 4.5:  no sound on HDMI.

Recapping:

Ubuntu 4.4.0-59: HDMI audio works properly

Mainline 4.4 (any): i915 drm driver does not seem to support Skylake,
HDMI audio not enumerated

All of the below kernels exhibit the same problem: HDMI produces no sound

Can you test the following two early Yakkety kernels:


4.6.0-10: 
https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/bootstrap/+build/10600030
4.8.0-11: 
https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/unstable/+build/10923199

With these kernels, you need to install both the linux-image and linux-
image-extra .deb packages.

[Kernel-packages] [Bug 1657994] Re: Regression: HDMI audio produces no sound (Skylake NUC)

2017-01-23 Thread Joseph Salisbury

I'd like to perform a bisect to figure out what commit caused this
regression. We need to identify the earliest kernel where the issue
started happening as well as the latest kernel that did not have this
issue.

Can you test the following kernels and report back? We are looking for
the first kernel version that exhibits this bug:

4.5 final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.5-wily/
4.6 final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.6-yakkety/
4.7 final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.7/
4.8-rc1:  http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.8-rc1/


You don't have to test every kernel, just up until the kernel that first
has this bug.

Thanks in advance!

[Kernel-packages] [Bug 1657994] Re: Regression: HDMI audio produces no sound (Skylake NUC)

2017-01-23 Thread Joseph Salisbury

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.10 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as
"Confirmed".


Thanks in advance.

Title:
  Regression:  HDMI audio produces no sound (Skylake NUC)

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  After upgrade from Xenial 16.04 to Yakkety 16.10, playing audio over HDMI no 
longer produces sound.
  * When booting with old kernel from Xenial (4.4.0-59), HDMI audio works fine
  * Audio from headphone jack works fine
  * Userspace seems to be happily playing to HDMI audio device, but no sound 
produced at HDMI sink (Samsung TV)

  Any of a wide range of pre-built mainline kernels fail to produce HDMI
  audio, but with a different failure mode (HDMI audio does not seem to
  be enumerated in the same way as in the Ubuntu kernels.)
