As far as I could tell from testing there is no pin which outputs to the headphone jack only. Instead the Internal speakers and headphone are the same output pin. When headphones are plugged in the internal speakers turn off.
I changed the Headphone pin to a Line Out since when I selected this output the Internal Speakers/Headphone Jack became disabled and the A/V Out remained on. When Internal Speakers was selected all three (Speakers, Headphone Jack, and A/V Out) were enabled. Then I feel as if the Headphone is actually a Line Out as it allows you to disable the internal speakers when you have external speakers attached to that A/V Out. There is no Internal Mic in this laptop (Its not in the spec sheet and I don't see one). The port replicator has 2 more outputs (RCA and Optical) and 1 more input (RCA), but I cannot test this until next month. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1400186 Title: [VGN-A690, Realtek ALC260] No sound at all internal speakers and headphone (Green out) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1400186/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
