[HDA-Intel - HDA Intel PCH, playback] Playback problem

[wjl]

Lenovo Thinkpad P50 with docking station

Issues: Headphone jack on station not detected; no sound (works without docking station)
Issues: Sound via HDMI on station not detected; no sound (works without docking station)

Since all outputs are routed via the Thunderbolt chip, my guess is that it's related to the pin setup (lenovo-dock) in Alsa. Without the dock, everything works, headphone/mic jack on the P50 itself is hotplug (switches from speaker to headphones right away).

Screenshots (with and without docking station) attached.

Thanks and LG,
Wolfgang

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

[Paul (paulnotpaul)]

I also have this problem. I have a Lenovo P50 with the Lenovo Thinkpad Workstation Dock (40A50230US) and the sound does not work when I use the dock.

I have:

Ubuntu 14.04.5 LTS

4.4.0-38-generic

[wjl (wolfgang-lonien)]

Still valid with kernel 4.4.0-45-generic which I've got today.

[Bob (caltinay)]

Kernel 4.7.6-1 on Debian also affected.

[Andreas Sperber (netcookie)]

As Paul I have this issue with a Lenovo P50 and the Dock.

Kernel is 4.4.0-57-generic with a Ubuntu 16.04.1 LTS.

Does anybody know when to expect a solution to this problem? It's really annoying working under those conditions!

[Bob (caltinay)]

Still not working with kernel 4.8.15-2 on Debian.

[coppermine (usptact)]

Still not working with kernel 4.9.12 on Ubuntu 16.10. Lenovo Thinkpad P50

[coppermine (usptact)]

I added the following line to /etc/modules files (use sudo):

snd-hda-codec-realtek

And get the audio working, both speakers and headphones. When the OS starts, there is a noticeable crack in speakers....

[Bob (caltinay)]

coppermine, are you referring to the dock or the laptop headphone jack?
I am now on kernel 4.9.6-3 in Debian and the dock's jack is still not working.
I have checked and the snd-hda-codec-realtek module is in fact loaded and used.

[Raz (razzz)]

I'm having the same issue. Running Ubuntu 16.04.2 LTS with kernel 4.8.0-45-generic. Audio jack on laptop works fine, but the audio jack on dock doesn't work at all.

[Stephen (enzed-rollins)]

I'll throw my hat in as well as someone who is experiencing this issue.

I don't have many technical details to share, since I'm not sure what would be helpful (or, frankly, where to find it), but I can share some behavioral insight:

- While not docked, my laptop's speakers work fine. The headphone jack works fine. Plugging in my headphones toggles some sound settings, as observed when I have my speakers muted, but I plug in my headphones and my audio automatically unmutes (in pactl, I can observe the port switching between analog-output-speaker and analog-output-headphones when I do this)
- While docked, my laptop's speakers work fine, and the headphone jack on my laptop also works. The behavior is identical to the undocked behavior. However, when I plug my headphones into the dock, my laptop speakers go silent but no sound goes through my headphones. Additionally, my active port does not change, as observed in pactl

[Mike Røntved (mikeyr)]

Same issue as #13 running Ubuntu 16.04 with kernel 4.10.0-37-generic, no issues in Windows 10.

same here
ubuntu 16.04
