I have got the same issue with Lenovo T540p and dock station connected to DP monitor. If my T540p docked then I have to manually selected DP output every time I boot it. If my laptop is undocked then fallback output (built-in stereo) is used however there is a caveat.
Unity-control-center and sound indicator/applet do not sync sound volume. That means if I switch to different output manually or fallback to stereo then sound volume stays the same from previously selected output. It is really annoying because I have to do it twice per day to change the output and adjust volume. Even if I tick Mute it may not help because I have to really adjust the volume before doing anything else. I am using my laptop docked and undocked every day so it is extremely annoying adjust output and volume. The bug is very easy to reproduce indeed. Taking in account that many people use dock stations with multiple outputs it must be fixed. It is obvious to remember previous output choice, keep sound volume for that output and fallback to built- in speakers in case no other output sources found restoring volume as well. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to unity-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1386379 Title: Audio Input switches after opening "Sound Settings/Input" Status in unity-control-center package in Ubuntu: Confirmed Bug description: I use my webcam microphone as my main audio input. Under the Sound Settings, Input tab, I have selected my webcam. The settings are saved after a reboot or a log without a problem. When I open the Sound Settings again, the input switches to the built-in audio automatically. This happens every time I open the Sound Settings, no matter what. I've selected hundreds of times my webcam, and as long as I don't go the the Sound Settings, the audio input won't switch. This is very frustrating and it never happened until Ubuntu 14.04. Is there a way I can make Ubuntu respect my selection? At least a workaround?
