Red Hat Bugzilla – Bug 503374
full-volume static from USB sound output when logging in (X) or switching users
Last modified: 2009-06-04 14:52:23 EDT
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
Steps to Reproduce:
1. log in or switch users
2. brace yourself
loud blast of static from speakers
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.
