Using a Lenovo L450 and Pro Dock it is not possible to play audio using the docks' 3,5mm port. This maybe is the same problem which has been fixed for other Lenovo models: - https://bugzilla.redhat.com/show_bug.cgi?id=1101386#c10 - https://bugs.launchpad.net/ubuntu/+source/linux/+bug/893611 (--> https://bugs.launchpad.net/ubuntu/+source/linux/+bug/893611/comments/12 ) I already tried to add several options to snd-hda-intel, not getting any better result. (model=thinkpad, model=lenovo, model=lenovo-dock) Using "id=PCH,HDMI index=0,1 model=lenovo-dock" it is possible to plug and unplug speakers directly to the notebook, otherwise the internal speakers would stay muted even if speakers are unplugged. But this is another topic... Is this the right place or should it be reported upstream? Reproducible: Always Steps to Reproduce: 1. Plug notebook into dock 2. Plug speakers into docks' audio port Actual Results: Internal speakers are muted (which is correct) and there is no sound coming from external speakers, sometimes only indefinable random noise. Expected Results: Sound should be played using plugged in external speakers See http://www.alsa-project.org/db/?f=43c20d0fd83b2ad3d7dba9f8d3bea29bad21d4d7 emerge --info Portage 2.2.14 (python
