[USB-Audio - Plantronics GameCom 780] Mic stops accepting input seemingly at random ( not enough bandwidth)

[Jim Podroskey]

The mic works after a new reboot. After some time, the mic stops receiving input. It still shows in the Input section of Sound Preferences, but the Input level no longer moves. In fact, the "graphic" of the input level bar seems to alter slightly. Each of the indicator bars seems to get a darker outline.

The symptom seems to to occur after launching Chrome (with Google talk plugin), Pidgin, Skype, or other things that might access the mic. However, it does not _always_ occur. Furthermore, the mic seems to start registering input (as seen on the Input Level indicator in sound preferences) again seemingly at random. The original poster in this thread (http://ubuntuforums.org/showthread.php?t=1180669) seem to describe my symptoms very well.

I've used the mic in Windows for an extended period of time. I've switched it to different USB jacks on my computer, including one that has a Blue Snowball microphone that has never "crapped out" like the Plantronics one is.

If there is any other information I can provide please let me know
