I have Ubuntu 14.04 64bit dual booted. When I connect something on front audio jack then rear audio is not working. I have tried changing analolog-output-headphones.conf file. After changing that alsamixer showing that both centre and surround not muted with full volum. Unfortunately no audio.

aplay -l

I have the same problem. When headphones are connected to front jack, ubuntu automatically turn off speakers. It is not configurable from the alsamixer... when front jack is connected, works only front jack. I'm very often using toggle between headphones to speakers, in ubuntu 12.04 it works programmatically but in 14.04 can only disconnect front jack, to use speakers. It is really frustrating, why its not configurable?


In alsamixer Auto-Mute Mode [Enabled/Disabled] worked for me, it toggle headphones and speakers, when front jack is connected, like a charm.

Welcome to Ask Ubuntu! You've posted this as an answer, and (as of your edit) this does seems like it is at least in part an answer to the question. But it's worded as though you're asking a separate, related question. To make this clearer for people searching for help (so they know this post might help them), and to decrease the likelihood that this post will be considered not-an-answer and deleted, I recommend rewording this, and also removing anything that's actually a question you want answered (rather than a proposed solution) and posting it as one. – Eliah Kagan Aug 25 '14 at 0:07
@yeneq6 That didn't work, Even changing with alsamixer is not working. – Shanoop Aug 25 '14 at 6:50
