Rafał Ochmański, as per http://www.dell.com/support/troubleshooting/us/en/19/Product/vostro-v131 an update is available for your BIOS (A06). If you update to this, does it change anything?
If not, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date Thank you for your understanding. ** Description changed: After connecting headphones with microphone to combo jack (TRRS), internal microphone stays active and headset microphone is not being used. - Similar reports have been filed, one here https://bugs.launchpad.net/ubuntu/+source/linux/+bug/950490 but adding - options snd-hda-intel model=laptop-dmic - to /etc/modprobe.d/alsa-base.conf doesn't solve the problem for me. - - This really should just work, there is absolutely no reason to prefer the internal mic which barely produces usable input anyway. - --- + --- ApportVersion: 2.6.1-0ubuntu6 Architecture: amd64 AudioDevicesInUse: - USER PID ACCESS COMMAND - /dev/snd/controlC0: rmo 3582 F.... pulseaudio + USER PID ACCESS COMMAND + /dev/snd/controlC0: rmo 3582 F.... pulseaudio DistroRelease: Ubuntu 12.10 HibernationDevice: RESUME=UUID=7c82e11d-4211-4789-90b6-7a20abd8aa82 InstallationDate: Installed on 2012-10-20 (13 days ago) InstallationMedia: Ubuntu 12.10 "Quantal Quetzal" - Release amd64 (20121017.5) MachineType: Dell Inc.
