The kernel (linux) contains alsa-kernel, or the actual sound driver. For all intents and purposes, the userspace alsa-lib is not relevant in this specific bug. So, "ALSA" is comprised of both a kernelspace portion (alsa-kernel) and a user-space portion (alsa-lib). In Karmic, PulseAudio is configured by default to rely on udev, via libudev, to provide information about which sound cards are available. (In previous Ubuntu versions hal was used, but hal is deprecated moving forward.) Very roughly, udev requires specifically formatted events for linux, so changing to an older kernel version that doesn't provide this information results in subtle bug symptoms. FWIW, you encounter them when you see that nodes are created in /dev instead of /dev/snd when you use Jaunty's linux with Karmic's udev. Hope that helps. -- no sound after upgrating to KK 9.10 https://bugs.launchpad.net/bugs/467747 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
