Bug 1543326

I went ahead and applied this to the F27 kernel with the 4.15 rebase. It will get picked up with that. F26 will get the fix when it goes to rebase as well. I'll let rawhide pick this up with the normal merging.

jupííí \ó/

Thx Laura

kernel-4.15.2-300.fc27 has been submitted as an update to Fedora 27. https://bodhi.fedoraproject.org/updates/FEDORA-2018-7336c2ba99

Still not working for me with T470 and Ultra dock on 4.15.2-300.fc27.x86_64. Does something else need to be updated?

In fact plugging in an audio cable into the dock causes roughly half of the boots to hang.

Vit, does the 4.15.2 update fix the problem for you?

It does not work :( Connecting headphones into dock crashes PA. See bug 1544507

Ugh, I guess I should drop the patch. I was planning on releasing 4.15.3 anyway so I'll drop it with that.

kernel-4.15.2-300.fc27 has been pushed to the Fedora 27 testing repository. If problems still persist, please make note of it in this bug report.
See https://fedoraproject.org/wiki/QA:Updates_Testing for
instructions on how to install test updates.
You can provide feedback for this update here: https://bodhi.fedoraproject.org/updates/FEDORA-2018-7336c2ba99

Would be probably good to drop this ticket from the Bodhi update.

Hi,

Just ran `sudo dnf update`, installed 4.15.3, rebooted, but I still can't hear anything when I plug my headset on my dock :
```
@localhost:~$ uname -a
Linux localhost.localdomain 4.15.3-300.fc27.x86_64 #1 SMP Tue Feb 13 17:02:01 UTC 2018 x86_64 x86_64 x86_64 GNU/
```
This is a `t470p` , not a `t470` .

Please ask me if I can provide anything to help you debug.

And thanks for working on that :)

Could you provide 'alsa-info.sh --no-upload' for a kernel with this patch? Also test the functionality with the ALSA tools only:

  $ speaker-test -D plughw:0
  $ alsamixer -c 0

(I assume that the first card is the HDA controller.)

alsa-info.sh --no-upload

$ speaker-test -D plughw:0

speaker-test 1.1.5

Playback device is plughw:0
Stream parameters are 48000Hz, S16_LE, 1 channels
Using 16 octaves of pink noise
Playback open error: -16,Device or resource busy

This looks suspicious, probably something from previous tests - it should be removed:


  !!Modprobe options (Sound related)

  snd_hda_intel: model=tpt460
  snd_hda_intel: patch=t470s.fw,t470s.fw,t470s.fw


> Playback open error: -16,Device or resource busy

Try to wait until PA release the sound device (close all audio apps) or kill PA and prevent respawn.

There you go :

$ speaker-test -D plughw:0

speaker-test 1.1.5

Les paramètres du flux sont 48000Hz, S16_LE, 1 canaux

Translation (yeah sorry i'm french):
```

Tried to play with `alsamixer -c 0` , but I couldn't get any sound whatsoever.
Please feel free to delete my attachment if it is redundant with the previous one.

Patrick, you don't use the kernel with the dock support patch. I think that the last Fedora kernel with the dock patch is 4.15.2 .

Thanks for the note, I'll wait for the patch to be present in stable then.
Sorry to have bothered you.

I removed that and the dock output now works! Thank you Jaroslav (although PA is still crashing plugging my headphones from dock to laptop, but that might be unrelated).

And it stopped working, probably after putting the LP into sleep. Not sure :/

Show output from 'alsa-info.sh --no-upload' for both working / non-working conditions.

*** Bug 1548063 has been marked as a duplicate of this bug. ***

There was published another patch, which might fix the suspend/resume issues:

https://bugzilla.kernel.org/show_bug.cgi?id=195161#c29

I am having issues with kernel 4.15.4, the T470s hangs on boot while in docking station, may that be related?

https://bugzilla.redhat.com/show_bug.cgi?id=1549169

Cannot reproduce any more, current kernel 4.18.7-200.fc28.x86_64
