[Bug 1205090] Re: 046d:c525 USB microphone quits working after a few seconds
keepitsimpleengr, as per http://www.foxconnsupport.com/download.aspx?models=en-us0000504&category=C000000001&brand=en-us0000002&Series=en-us0000012&chipset=en-us0000160&keywords=&sort= an update is available for your BIOS (A34F1P04). If you update to this following https://help.ubuntu.com/community/BiosUpdate , does it change anything? If it doesn't, 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
Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful.
For more on BIOS updates and linux, please see

.
Thank you for your understanding.

Title:
046d:c525 USB microphone quits working after a few seconds
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
On my Mythbuntu 12.04.2 HTPC, my USB microphone (Logitech AK5370)
works for a few seconds, then stops producing signal from audio input.
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.

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".
