ALSA backport missing NVIDIA GPU codec IDs to patch table to Ubuntu 16.04 LTS Kernel

[David Coronel]

Add support for 4/6/8 channel sound in 16.04 LTS kernel for future GPUs.

This commit[1] first introduced in "Thu Jul 13 19:27:39 2017"[2] has what is needed base on discussion we had with nvidia:

ALSA: hda - Add missing NVIDIA GPU codec IDs to patch table

Add codec IDs for several recently released, pending, and historical NVIDIA GPU audio controllers to the patch table, to allow the correct patch functions to be selected for them.

[2] - git describe --contains 74ec118152ea494a25ebb677cbc83a75c982ac5f
v4.13-rc3~21^2~5

[Eric Desrochers (slashd)]

Patch is already found in v4.13 (ubuntu-artful)

$ git describe --contains 74ec118152ea494a25ebb677cbc83a75c982ac5f
v4.13~13^2~22

v4.4 (ubuntu-xenial) doesn't have the patch.

Since this seems trivial, and apply cleanly, and I'll proceed with the SRU (after verification) and see what kernel-team says.

I have provided a test kernel "4.4.0-111-generic #134+hf166707v20180117b5" for pre-SRU verification and it has been brought to my attention the following statement:

-----------------------------------------
Our QA was able to test with the kernel you provided, and things look good!

I've upgraded the kernel and issue did not repro.

Config :
GPU Driver 384.111
Kernel 4.4.0-111-generic

# uname -a
Linux <HOSTNAME> 4.4.0-111-generic #134+hf166707v20180117b5-Ubuntu SMP Wed Jan 17 19:04:03 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

I've verified output through all channels (7.1) using Test Sound option in Sound Setting + by running different 4,6 channel clips using aplay.
Connections were made using DP-HDMI dongle (accell) + DENON-AVR

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-xenial' to 'verification-done-xenial'. If the problem still exists, change the tag 'verification-needed-xenial' to 'verification-failed-xenial'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

[Jamie Nguyen (jamien)]

I've let our QA (India-based) know about this. I'll update as soon as they've had a chance to verify.

[Jamie Nguyen (jamien)]

Verified by our QA. Changing tag to "verification-done-xenial".

============================================
Thanks, Jamie, below steps were helpful.
This bug did not repro with [Ubuntu 16.04] + kernel 4.4.0-116-generic : 384.111 (R384_00)

I've verified output through all channels (7.1) using Test Sound option in Sound Setting + by running different 4,6 channel clips using aplay.
