RS780M HDMI audio broken since 4.9.180

[dufresnep]

RS880M HDMI audio is broken since kernel 4.9.180 (4.9.175 ok ).
Broken in the sense that HDMI profile is unavailable because unplugged in pavucontrol.

Not my laptop ( a friend ).

System tested is Mint 20.3 Cinnamon.
Latest kernel tested: BOOT_IMAGE=/boot/vmlinuz-5.15.0-50-generic
Kernel tested from https://kernel.ubuntu.com/~kernel-ppa/mainline/ (generic amd64)

Not my laptop ( a friend ).

If the kernel is installed from Ubuntu's Mainline, there's a good chance that it isn't officially supported by Mint.

But, this is nonetheless an occasion for friends to snack & chat, and bring the laptop along. There's wifi to share, yes? If not, you could temporarily tether the laptop to a smartphone for Internet access.


To post essential details about the PC setup: Plug in all relevant dongles, accessories, and peripherals. Then

Open a Terminal (ctrl-alt-T), then copy-and-paste the following long line of green text into the Terminal window, then tap Enter ...

Code: Select all

C=code];echo "[$C`inxi -Fxxxmprzc0 --usb;mokutil --sb;cat /proc/cmdline;dkms status;lsusb;lsblk -fir;lspci -nnk`[/$C"|xed -

Within a moment, xed text editor pops open, showing technical data that's useful for others to analyze PC & peripheral issues.

Copy-and-paste everything from xed into a Reply here. < The required [code] tags have been added for you />


Disable Secure Boot in your BIOS, as it's known to interfere with device drivers & firmware. If you run Windows on the same PC as Linux, disable Windows Fast Startup, otherwise it can leave your hardware in a zombie state at any time. When you exit Windows, to boot into Linux, do a full Shutdown, not just a Restart.

Will have to wait a bit I return see that friend.

Note: /etc/default/grub have radeon.audio=1 ... did not helped with later kernel than 4.9.175... have not tested remove it in 4.9.175.

Unsure if it is better to execute suggested command on broken version or on working version.

I asked on Ubuntu kernel team mailing list help to identify which versions it would correspond in vanilla Linux.

For similar problem, others have said that the following command may help:

Unsure if it is better to execute suggested command on broken version or on working version.

Run this command-line on the configuration that you expect to use:

4.9.178 is broken too.
4.9.178 is 2019-05-21 18:49:02 +0200.

[dufresnep]

With 4.9.177, I am unable to generate unsigned kernel packages...
Some crypto package complained: camelia_avx, or something similar.
At first, because it was an fopen related to SSL problem, I thought that changing the modules to in the kernel, rather than modules would work.
It did not.

I followed https://github.com/lwfinger/rtw89/issues/78 that lead me to:
https://github.com/lwfinger/rtw89/issues/74

Now I still get:

And I think I need to put back the .pem path in .config.

It has come to my mind that maybe snd-hda-intel could use some crypto modules signed with an unpresent key on the system...
Frankly a very wild guess from me.

Still... I think the laptop of my friend might be old enough to badly manage keys... and strangely seem to be able to boot in UEFI while not showing any UEFI options in BIOS.

[dufresnep]

I just mv .config on an other name, then "make menuconfig", saved, and try to continue:

Looks like it will finish fine now that I have commented out the line in .config with canonical... .pem.

Will call my friend to go test 4.9.176 and 4.9.177 on his laptop with his TV.
Will check if it ask my to enroll the key I generated, and if it change something I do or not.

[dufresnep]

Both 4.9.176 and 4.9.177 worked.
It did not ask any key (or password) for 4.9.177.
So I am beginning to search between 4.9.177 working, and 4.9.178 not working.

I have come to realize that the offending commit I mentioned is a merge, and so is made of many commits.
So I have accepted that I need to do a git bitsect command to find the real commit among including the commits in the merge.
But I did like done it only one, long ago, and needed to refresh my memory.
Well, I just done this beginner's guide to git bitsect: https://www.metaltoad.com/blog/beginner ... limination

So now with the real stuff.

Could you please explain how what you are doing is relevant to Linux Mint?

Linux Mint does not use the 4.9 kernel series so saying your friend updated from 4.9 kernel to another 4.9 kernel appears to have no meaning at all for Linux Mint users.

This is a support forum for Linux Mint. Please provide the Linux Mint system information and explain how what you are doing is relevant to Linux Mint users.

The problem was first discovered in Mint 20.2.
I discovered that older kernels was not having problems with HDMI audio.
I am searching the specific commit that cause the HDMI device to become not available even when well plugged.

Bug present in 6.0.1 kernel from https://kernel.ubuntu.com/~kernel-ppa/m ... _amd64.deb

[SMG]

The problem was first discovered in Mint 20.2.

The default kernel for LM20.2 is the 5.4 LTS kernel. One can also use the 5.15 LTS kernel (which is LTS for LM21) in LM20.2.

If someone runs into an issue with a kernel breaking something, one usually tries the prior version. For example, if there is a problem with 5.15.0-50, then one would try 5.15.0-48 or one of the 5.4 kernels.

Canonical starts with the mainline 5.4 or 5.15 kernels and then makes cumulative changes to it as described in 5.4.0-131.147 changelog and 5.15.0-52.58 changelog. The changes are usually either bug fixes or backporting fixes from newer kernels.

Presumably, the LM20.2 install did work at one point which means a 5.4 kernel (or a 5.15 kernel) did work so I am still confused as to why you are bisecting 4.9 mainline kernels. Linux Mint main edition does not use mainline kernels. (LMDE uses mainline kernels, but LM20.2 is not LMDE.)
