Description Bill McGonigle 2009-05-31 16:08:24 UTC
Description of problem:

When logging in or switching users, the speakers connected to a USB audio device (Griffin iMic) blast static at full volume for a second or two.  I rarely set bugs to 'urgent', and I'd like to set it down if somebody can confirm this is merely annoying/frightening and nobody is going to blow out their speakers, but potential hardware damage might be an appropriate use.

Version-Release number of selected component (if applicable):

  fedora 11 rawhide

How reproducible:


Steps to Reproduce:
1. log in or switch users
2. brace yourself
Actual results:

  loud blast of static from speakers

Expected results:

  silent transition

Additional info:

In Fedora 10 this doesn't happen, and the speakers were my primary audio device.  In Fedora 11 I don't even see the device in the mixer but when I unplug the iMic I'm asked if I want to forget about the device.  There might be two problems here, the detection of this particular device, and the proper handling of a device that's not properly detected.

  Bus 001 Device 020: ID 077d:0223 Griffin Technology IMic Audio In/Out

I mostly guessed on this bug's component, please re-assign if needed.
