As a result, some applications cannot get sound from the microphone. The Input tab of the Sound window lists no device. I have a workround which is to disconnect and then connect the microphone after I have logged in. Interestingly, the audacity application can access the microphone when the system says that the device does not exist ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: alsa-base 1.0.25+dfsg-0ubuntu4 ProcVersionSignature: Ubuntu 3.2.0-67.101-generic 3.2.60 Uname: Linux 3.2.0-67-generic x86_64 ApportVersion: 2.14.1-0ubuntu3.3 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: tim 2060 F.... pulseaudio CurrentDesktop: Unity Date: Fri Sep 5 00:12:39 2014 InstallationDate: Installed on 2011-07-29 (1133 days ago) InstallationMedia: Ubuntu 11.04 "Natty Narwhal" - Release amd64 (20110427.1) PackageArchitecture: all SourcePackage: alsa-driver Symptom: audio Symptom_AlsaRecordingTest: ALSA recording test through plughw:Intel failed Symptom_Card: Built-in Audio - HDA Intel Symptom_DevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: tim 2060 F.... pulseaudio Symptom_Jack: Pink Mic, Rear Symptom_Type: No sound at all Title: [G41MT-S2P, VIA VT2020, Pink Mic, Rear] No sound at all UpgradeStatus: Upgraded to trusty on 2014-08-15 (20 days ago) dmi.bios.date: 12/31/2010 dmi.bios.vendor: Award Software International, Inc. dmi.bios.version: F1 dmi.board.name: G41MT-S2P dmi.board.vendor: Gigabyte Technology Co., Ltd. dmi.board.version: x.x dmi.chassis.type: 3 dmi.chassis.vendor: Gigabyte Technology Co., Ltd. dmi.modalias: dmi:bvnAwardSoftwareInternational,Inc.:bvrF1:bd12/31/2010:svnGigabyteTechnologyCo.,Ltd.:pnG41MT-S2P:pvr:rvnGigabyteTechnologyCo.,Ltd.:rnG41MT-S2P:rvrx.x:cvnGigabyteTechnologyCo.,Ltd.:ct3:cvr: dmi.product.name: G41MT-S2P dmi.sys.vendor: Gigabyte Technology Co., Ltd.
