[Bug 1462977] [NEW] Thinkpad T440s - Sound muted when docked to docking station

[Fabian Franzen]

Public bug reported:

Hi everyone,

when I dock my Thinkpad T440s to my docking station, the sound channel
for the speakers connected to the docking station audio jack are muted
by default. If I run the following command after docking

amixer --card 1 sset 'Speaker+LO' 100%

the sound starts working. Unfortunatly I have to run this command every
time I am docking the system to the docking station. Furthermore there
is specific volume slider is not shown in the audio setttings of Unity.
So this command could only be a temporary workaround... The internal
speakers and the headphones jack of my laptop does not have these
problems.

It would be really nice if the audio output of the docking stations
stays unmuted, when i connect the laptop to the docking station.

Maybe this bug is related to
https://bugzilla.redhat.com/show_bug.cgi?id=1101386, but the workaround
proposed there does not work for me.

Okay... How can I check this? I am sorry, but I am pretty new to the
internals alsa / pulseaudio... I am not sure how can I help you best
there to narrow down the issue...

And the speakers are connected to the "1x Stereo/Mic Combo Audio Port"
mentioned in the device specification of Lenovo. Nothing is connected to
the audio port directly at the laptop (that works fine by the way).

I am using the ThinkPad Pro Dock (Type 40A1). That should be this one

[Bug 1447224] Re: Regression: Unable to select audio or subtitle tracks

[Fabian Franzen]

The patch proposed in
 solved the
problem with VLC (and also for LyX, see link before).

Unfortunately the problem with totem still persists...

I am also affected by this bug. First I thought it was a configuration
mistake of mine, so I created a question at askubuntu.com where i
describe the problem: http://askubuntu.com/questions/617296/unable-to-

[Bug 1448272] Re: White line between the interface and the application window title

[Fabian Franzen]

I am not familar with the rhythembox codebase, but it seems to be an
error in styles.css that causes the white line.

As a workaround you can directly apply the patch attached to the
styles.css in your system which can be found in /usr/share/rhytembox.
When rhytembox is started next time the white line should be gone.

If some package maintainer reads this, feel free to adapt the patch, but
I have only done very limited testing.

** Patch added: "style.css patch to remove the 1px border of the primary 
toolbar"
