Red Hat Bugzilla – Bug 812165
3.x kernels break sound of laptop docking
Last modified: 2012-04-12 19:51:21 EDT
Description of problem:
I have a Thinkpad X201 with docking and a set of speakers attached to it. All of Fedora's 3.x kernels break sound output of the docking, the speakers remain silent. When I however plug the speakers directly into the laptop output, they work fine.
The docking does not have a sound card, just line-out and mic-in. If I plug the speakers into the docking or the laptop itself, the internal speaker is turned of, but I guess this is done in hardware.
Version-Release number of selected component (if applicable):
For testing I installed an kernel-220.127.116.11-1.fc15.x86_64 and sound on the docking works fine.
Steps to Reproduce:
1. upgrade from F15 to F17
no more sound.
Let there be sound!
