I have also just been affected by this bug. I have been using Ubuntu 14.04 fine from June until now, but I just had a lockup which caused this issue for me.
I have the Asus Xonar DS PCI sound card in an Asus M5A97 EVO motherboard. I was running DOTA2 via Steam at the same time as Mumble 1.2.8, with the audio outputted to my headphones, and the microphone on the soundcard selected (and being picked up from my headphones). I Alt-Tabbed from the game to alter the volume for Steam / DOTA2 in the Applications tab of Sound, and when I returned to the game I got a lockup which required that I restart my machine. After restart I now have the behaviour described in this bug - the SPDIF input is selected by default and if I select Microphone, and come back into Sound the SPDIF input has been reselected. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1334329 Title: Sound input settings not saved Status in “alsa-driver” package in Ubuntu: Confirmed Bug description: When attempting to set my preferred sound input device, simply leaving sound preferences and going back to sound preferences, and selecting input, causes the default SPDIF to be selected again, and not the internal microphone I preferred.

It's just the sound preferences. 3) What you expected to happen For my selected sound input to be saved. 4) What happened instead Keeps defaulting to the top sound input ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: alsa-base 1.0.25+dfsg-0ubuntu4 ProcVersionSignature: Ubuntu 3.13.0-29.53-generic 3.13.11.2 Uname: Linux 3.13.0-29-generic x86_64 NonfreeKernelModules: wl ApportVersion: 2.14.1-0ubuntu3.2 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: brandon 23953 F.... pulseaudio /dev/snd/controlC0: brandon 23953 F.... pulseaudio CurrentDesktop: Unity Date: Wed Jun 25 11:20:14 2014 InstallationDate: Installed on 2014-04-26 (60 days ago) InstallationMedia: Ubuntu 14.04 LTS "Trusty Tahr" - Release amd64 (20140417) PackageArchitecture: all SourcePackage: alsa-driver Symptom: audio Symptom_AlsaRecordingTest: ALSA recording test through plughw:PCH successful Symptom_Card: Caicos HDMI Audio [Radeon HD 6400 Series] - HDA ATI HDMI Symptom_PulseAudioRecordingTest: PulseAudio recording test through plughw:PCH successful Symptom_Type: None of the above Title: [HDA-Intel - HDA Intel PCH, recording] Recording problem UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 01/24/12 dmi.bios.vendor: Apple Inc. dmi.bios.version: MBP81.88Z.0047.B27.1201241646 dmi.board.asset.tag: Base Board Asset Tag# dmi.board.name: Mac-94245A3940C91C80 dmi.board.vendor: Apple Inc. dmi.board.version: MacBookPro8,2 dmi.chassis.type: 10 dmi.chassis.vendor: Apple Inc. dmi.chassis.version: Mac-94245A3940C91C80 dmi.modalias: dmi:bvnAppleInc.:bvrMBP81.88Z.0047.B27.1201241646:bd01/24/12:svnAppleInc.:pnMacBookPro8,2:pvr1.0:rvnAppleInc.:rnMac-94245A3940C91C80:rvrMacBookPro8,2:cvnAppleInc.:ct10:cvrMac-94245A3940C91C80: dmi.product.name: MacBookPro8,2 dmi.product.version: 1.0 dmi.sys.vendor: Apple Inc.
