I have an ASUS 1015E laptop that has a single 3.5mm audio combo port for both mic and headphone (TRRS connector plugs go in there). So I use headsets that come in a single wire which has both headphone and mic functionality. (Like the ones that come with smartphones).

This headset works perfect on windows where the integrated mic of the laptop is disabled in lieu of the headset's mic whenever it is connected. However, that's not the case on my Ubuntu 13.10 (x86_64).

How can I fix this?
