I have a major problem. I recently bought an Acer E1 - Ubuntu 13.10 as OS. (My first foray into Linux after getting exasperated over a bug in anoter OS).
Since a bomb blast some years ago, I am heavily hearing impaired. However, with my headphones, I have been able to listen to the radio - and maintain a good relationship to my neighbours.
This solution does not work in Ubuntu. My headphones are dead. (the external speakers do not work either).
I suspect, that the reason is simple. In system settings, the sound is set to play through the speakers in the built in audio. I am trying to add an external option - but just do not get it.
(In another thread clicking on the connector is suggested. There is no such option here - at least not wot I see).
