[Bug 913686] New: Jack detection for Thinkpad T420 in docking station regresses to openSUSE 13.1
http://bugzilla.opensuse.org/show_bug.cgi?id=913686 Bug ID: 913686 Summary: Jack detection for Thinkpad T420 in docking station regresses to openSUSE 13.1 Classification: openSUSE Product: openSUSE Distribution Version: 13.2 Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Sound Assignee: tiwai@suse.com Reporter: markus.zimmermann@nethead.at QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- I am using a Thinkpad T420 in a docking station. I use the audio out of the docking station. When I play music the sound is working fine coming from the docking station. However, when I plug in my headphones to the Thinkpad audio out I expect that the sound of the docking station is muted but sound is then coming out of both, the docking station and headphones. This was working with openSUSE 13.1. Furthermore when I unplug the audio of the docking station and headphones I expect that the Thinkpad speakers are used. However, this only works when I plugout the audio of the docking station as last. When I plug out the headphones as last the speakers are muted. -- You are receiving this mail because: You are on the CC list for the bug.

I logged out of my KDE session and switched to a console. I could not make it work with the alsamixer. I cannot find a configuration of the mixer where sound is only coming out of the headphones but not of the dockingstation when both are plugged in.
What do you mean "could not make it work with the alsamixer"? You could start alsamixer with -c0 or -c1 option and adjust each mixer element, right? As long as "Auto-Mute Mode" is set, the driver decides which output to use per jack state, so you cannot choose it freely when plugging multiple jacks. If you want to play *only* from the laptop headphone or from the dock headphone, you need to disable the auto-mute feature and adjust the mixer switch manually. The alsa-info outputs from comment 6 and 7 indicate that the pulseaudio is still running and controlling the mixer. I vaguely remember of a similar issue with the PA version of openSUSE 13.1. Is it possible to upgrade to openSUSE 13.2? Basically I'm not going to debug such a PA version any longer actively, it'd be great if we can align to the latest status. -- You are receiving this mail because: You are on the CC list for the bug.

Disabling "Auto-Mute Mode" and then adjusting the levels of the mixers does not work as I expect it to. When I plugin the the jack in the dockingstation and my headphones they both have sound output and adjusting the mixers adjusts both of their levels.
If you want more finer volume behavior adjustment, report it to PA upstream. The shared volume can't be avoided as it's a hardware limitation: the chip has no individual volume control for all three outputs, thus one of them has to be shared with another. The mute/unmute could be done, though. -- You are receiving this mail because: You are on the CC list for the bug.

I would be happy with the old behavior of openSUSE 13.1 where only one jack of the three, outputs audio. Priority would be 1. Thinkpad jack 2. Docking jack 3. Thinkpad speakers If the a jack is detected in the thinkpad it should only sound from there. I think that this was a good default behavior and that the current behavior of 13.2 is confusing.
This is still the behavior of the kernel driver itself (when "Auto-Mute" is enabled). If behaving differently, it's PulseAudio. -- You are receiving this mail because: You are on the CC list for the bug.

Could you tell me some configuration files/options so I can narrow down the problem?
I don't know of any PA option to change the output priority dynamically. That's why I suggested to raise it to PA upstream. -- You are receiving this mail because: You are on the CC list for the bug.

@Takashi: what is "upstream" in this case?
PulseAudio upstream. -- You are receiving this mail because: You are on the CC list for the bug.
