Comment 4 Dario Castellarin 2010-11-21 01:27:01 UTC

This update broke sound on my laptop (Compal JFL92) on F14 x86_64. The bug is 100% reproducible:

1. Install the udev/dracut update
2. Rebuild the initramfs image (dracut -f)
3. Reboot

Pulseaudio won't find any sound card when running module-udev-detect, and will fall back to dummy audio output.
If I downgrade udev and dracut, and rebuild the initramfs image, the problem doesn't appear anymore.

Later tomorrow I should be able to test it on other systems.
