The system recognizes it there, it just stays mute. This happens on all USB ports. It has worked fine for months. I`m confident it's not the hardware because the microphone works fine with Win7 and also on other computers. $ uname -a Linux KISE-066 3.5.0-34-generic #55~precise1-Ubuntu SMP Fri Jun 7 16:25:50 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux $ lsusb Bus 001 Device 002: ID 05e3:0608 Genesys Logic, Inc.

MX Revolution Cordless Mouse Re-install of Mythbuntu is impracticable. -------------- I tried the fix in [this question][1] (changing gstreamer settings) but it didn't work. After every change, the mic would work as seen on Pulse Audio Volume Control for a few seconds, then the "level" on the level caught at the few seconds when it stopped working. ---------------- I installed Audacity to monitor the microphone's input level. With the settings ALSA > default > AK5370:USB Audio (hw:1,0): Line 0 the level meter shows the mic working. ----------------- Using a "trick" from the old days, I re-installed the following... gstreamer0.10-pulseaudio (version 0.10.31-1ubuntu1.2) will be re-installed libcanberra-pulse (version 0.28-3ubuntu3) will be re-installed libpulse-mainloop-glib0 (version 1:1.1-0ubuntu15.3) will be re-installed libpulse-mainloop-glib0:i386 (version 1:1.1-0ubuntu15.3) will be re-installed libpulse0 (version 1:1.1-0ubuntu15.3) will be re-installed libpulse0:i386 (version 1:1.1-0ubuntu15.3) will be re-installed libpulsedsp (version 1:1.1-0ubuntu15.3) will be re-installed libpulsedsp:i386 (version 1:1.1-0ubuntu15.3) will be re-installed libusb-0.1-4 (version 2:0.1.12-20) will be re-installed libusb-0.1-4:i386 (version 2:0.1.12-20) will be re-installed libusb-1.0-0 (version 2:1.0.9~rc3-2ubuntu1) will be re-installed paman (version 0.9.4-1ubuntu3) will be re-installed paprefs (version 0.9.10-0ubuntu1) will be re-installed pavucontrol (version 0.99.2-1build1) will be re-installed pavumeter (version 0.9.3-1ubuntu2) will be re-installed pulseaudio (version 1:1.1-0ubuntu15.3) will be re-installed pulseaudio-module-gconf (version 1:1.1-0ubuntu15.3) will be re-installed pulseaudio-module-x11 (version 1:1.1-0ubuntu15.3) will be re-installed pulseaudio-module-zeroconf (version 1:1.1-0ubuntu15.3) will be re-installed pulseaudio-utils (version 1:1.1-0ubuntu15.3) will be re-installed usbutils (version 1:005-1) will be re-installed ...and rebooted. No help. -------------- I have discovered that after closing and reopening Pulse Audio Volume Control, the microphone volume level will show the microphone working fo a few seconds, then "freezing". ???
