Bug Description

Using Feisty Distro, attempt to upgrade only kernel to Hardy: 2.6.24-7. Gets segfault when in initramfs (have reported that bug as well), so build the 2.6.24-7 source by hand, changing the drivers necessary for my Motherboard *Sata, ext3, scsi) to be built-in.

Kernel boots and appears to work fine except the audio is now hissing (acts like an amplifier is turned all the way up), then with some media (for example, the intro screen to Chromium) I get the crackle of an overdriven amplifier, like it is being clipped.

I tried installing Pulse Audio, but that had no effect, Have adjusted all controls in Kmix and muted everything possible, toggled switches, with no effect.

Care to retest with the latest 2.6.24-10 kernel? Also, you might want to try installing the linux-ubuntu-modules package as that has an updated version of ALSA. Thanks.
