A very similar issue on another Inspiron 5437 with 12.04.3 fresh install, but with different intel audio chip [8086:0a0c].
External headset microphone through single jack will not be detected, but headphone works normally. Also internal microphone and speaker works fine. ** Attachment added: "alsa-info pciid 8086:0a0c 201304-13208" https://bugs.launchpad.net/ubuntu/+source/linux-lts-raring/+bug/1249956/+attachment/3905289/+files/alsa-info_201304-13208.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1249956 Title: [Dell Latitude E6440] External microphone cannot be detected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lts-raring/+bug/1249956/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
